ar under the forthcoming director-generalship of Harcourt-Smith.
“I thought you might like to see the list of ports and airports we have to keep an eye on, John,” said Bright.
Preston studied the information put before him. Were there really that number of airports with flights originating or terminating outside the British Isles? And the list of ports able to receive commercial cargo vessels arriving from foreign ports went on for pages. He sighed and started to read.
The following day, Petrofsky found what he was looking for. Operating on a policy of making different purchases in different towns in the Suffolk/Essex area, he had gone to Stowmarket. The motorcycle was a BMW shaft-drive K100, not new but in excellent condition, a big, powerful machine, three years old but with only 22,000 miles on the clock. The same shop also stocked the accessories—black leather trousers and jacket, gauntlets, zip-sided jackboots, and crash helmet with dark, slide-down visor. He bought a complete outfit.
A twenty-percent deposit secured him the motorcycle, but not to take away. He asked for saddlebags to be fitted outside the rear wheel, with a lockable fiberglass box on top of them, and was told he could collect the machine with its fittings in two days.
From a phone booth he called the insurance broker in Colchester and gave him the registration number of the BMW. The broker was confident he could have temporary thirty-day insurance coverage by the next day. He would mail the policy to the Great White Horse hotel in Ipswich.
From Stowmarket, Petrofsky motored north to Thetford, just over the county border in Norfolk. There was nothing particular about Thetford; it just lay approximately in the line he needed. He found what he wanted just after lunch. On Magdalen Street, between No. 13A and the Salvation Army hall, is a recessed rectangular yard containing thirty garages. One had a TO LET notice stuck on its door.
He traced the owner, who lived locally, and rented the garage for three months, paying in cash, and was given the key. The garage was small and musty, but would serve his purpose admirably. The owner had been happy to take tax-free cash and had asked for no form of identification. Petrofsky had therefore given him a fictitious name and address.
He stored his motorcycle leathers, helmet, and boots in the garage, and during what remained of the afternoon bought two ten-gallon plastic drums from two different shops, filled them with gasoline at two different stations, and locked them in the garage as well. At sundown he motored back to Ipswich and told the hotel receptionist that he would be checking out the following morning.
Preston realized he was becoming bored to the point of distraction. He had been in the job only two days, and they had been spent reading files.
He sat over lunch in the canteen and thought seriously of taking early retirement. That presented two problems. First, it would not be easy for a man in his mid-forties to get good employment, the more so since his arcane qualifications were hardly the type that the big corporations would find of irresistible interest.
The second concern was his loyalty to Sir Bernard Hemmings. Preston had been in the service only six years, but the Old Man had been very good to him. He liked Sir Bernard and he knew the knives were out for the ailing Director-General.
The ultimate decision on who will be head of MI5 or Chief of MI6 in Britain lies with a committee of so-called Wise Men. In the case of MI5, these would normally be the Permanent Under Secretary at the Home Office (the ministry that controls Five), plus the PUS at Defense, the Cabinet Secretary, and the Chairman of the Joint Intelligence Committee.
These would “recommend” a favored candidate to the Home Secretary and Prime Minister, the two senior politicians involved. It would be unusual for the politicians to decline the recommendation of the Wise Men.
But before they made a decision the mandarins would take soundings in their own inimitable way. There would be discreet lunches in clubs, drinks at bars, murmured discussions over coffee. In the case of the proposed Director-General of MI5, the Chief of the SIS would be consulted, but since Sir Nigel Irvine was himself moving close to retirement, he would need a very good reason for advising against a leading candidate for the other intelligence service. After all, he would not have to work with the man.
Among the most influential of the sources sounded out by the Wise Men would be the outgoing DG of Five himself. Preston knew that an honorable man like Sir Bernard Hemmings would feel bound to take a straw poll of his own heads of section throughout the six branches of the service. That straw poll would weigh heavily with him, whatever his personal feelings might be. Not for nothing had Brian Harcourt-Smith used his increasing dominance in the day-to-day running of the service to place one after another of his protégés at the head of the numerous sections.
Preston was in no doubt that Harcourt-Smith would like him to leave before the autumn, to follow two or three others who had gone into civilian life over the past twelve months.
“Sod him,” he remarked to no one in particular in a largely empty canteen. “I’ll stay.”
While Preston was at lunch, Petrofsky left the hotel, his luggage by now augmented by a large suitcase full of clothes that he had bought locally. He told the receptionist that he would be moving to the Norfolk area and that any mail arriving for him should be held pending collection. He rang the insurance broker in Colchester and learned that the temporary coverage for the motorcycle had been issued. The Russian asked the broker not to mail it; he would collect it himself. This he did immediately, and late that afternoon moved into 12 Cherryhayes Close. He spent part of the night working carefully with his one-time pads, preparing a coded message that no computer would break. Code-breaking, he knew, was based on patterns and repetitions, however sophisticated the computer used to crack the code. Using a one-time pad for each word of a short message left no patterns and no repetitions.
The next morning, Saturday, he drove to Thetford, garaged his car, and took a local taxi to Stowmarket. Here, with a certified check, he paid the balance of the price of the BMW, borrowed the toilet to change into his leathers and crash helmet, which he had brought in a canvas bag, stuffed the bag and his ordinary jacket, trousers, and shoes into the saddlebags, and rode away.
It was a long ride and took him many hours. It was not until late evening that he arrived back at Thetford, changed clothes, exchanged motorcycle for family sedan, and motored sedately back to Cherryhayes Close, Ipswich, where he arrived at midnight. He was not observed, but if he had been, it would have been as “that nice young Mr. Ross who moved into Number Twelve yesterday.”
On a Saturday evening, Master Sergeant Averell Cook of the U.S. Army would have preferred to be dating his girlfriend in nearby Bedford. Or even playing pool with friends in the commissary. Instead he was taking the swing shift at the joint British-American listening station at Chicksands.
The “head office” of the British electronic monitoring and code-breaking complex is at the Government Communications Headquarters at Cheltenham, Gloucestershire, in the south of England. But GCHQ has outstations in various parts of the country, and one of them, Chicksands, in Bedfordshire, is run jointly by GCHQ and the American National Security Agency.
The days when attentive men sat hunched into earphones trying to pick up and record the manual tapping of a Morse key operated by some German agent in Britain are long gone. In the business of listening, analyzing, filtering the innocent from the not-so-innocent, recording the latter, and decoding, computers have taken over.
Sergeant Cook was confident, and rightly so, that if any of the forest of aerials above him picked up an electronic whisper, it would pass that whisper to the banks of computers below. The scanning of the bands was automatic and the recording of any whisper in the ether that should not be there equally automatic. If such a whisper occurred, the eternally watchful computer would trigger its own hit button deep inside its own multicolored entrails, record the transmission, take an immediate bearing on its source, instruct other, brother computers across the country to take a crossbearing, and alert Serg
eant Cook.
At 11:43 p.m., something caused the master computer to operate its own hit button. Something or someone had transmitted what was not expected, and out of the whirling kaleidoscope of electronic signals that fill the air of this planet twenty-four hours in every day, the computer had noticed and traced it. Sergeant Cook noted the warning signal and reached for a telephone.
What the computer had picked up was a “squirt,” a brief shriek of sound that lasted only a few seconds and would make no sense to the human ear. A squirt is the end product of quite a laborious procedure in the sending of clandestine messages. First the message is written out in clear and made as brief as possible. Then it is encoded, but it still remains a list of letters or figures. The encoded message is tapped out on a Morse key, not to a listening world but to a tape machine. The tape is then speeded up to an extreme degree, so that the dots and dashes that make up the transmission are telescoped, to emerge as a single screech lasting only a few seconds. When the transmitter is ready to go, the operator simply sends that single screech, then packs up his set and moves sharply somewhere else.
Within ten minutes that Saturday night, the triangulators had pinpointed the spot from which the screech had come. Other computers, at Menwith Hill in Yorkshire and Brawdy in Wales, had also caught the brief squirt transmission and taken a bearing. When the local police got there, the spot turned out to be the shoulder of a lonely road high in the Derbyshire Peak District. There was no one there.
In due course the message went to Cheltenham and was slowed down to a pace at which the dots and dashes could be transcribed into letters. But after twenty-four hours of going through the electronic brains called the code-breakers, the answer was still a big zero.
