'Sir, basing on the last occasion Drake exited Red China, sir, and updating our assessment to the situation as of now, we and navy int. between us, sir -'
'Murphy, Murphy,' put in Martello quite kindly, cease off a little, will you, friend? This isn't training school any more, okay? Loosen your girdle, will you, son?'
'Sir. One. Weather,' Murphy said, quite untouched by this appeal. 'April and May are the transitional months, sir, between the north-east monsoons and the beginning of the south-west monsoons. Forecasts day-to-day are unpredictable, sir, but no extreme conditions are foreseen for the trip.' He was using the pointer to show the line from Swatow southward to the fishing beds, then from the fishing beds northwest past Hong Kong up the Pearl River to Canton.
'Fog?' Martello said.
'Fog is traditional for the season and cloud is anticipated at six to seven oktas, sir.'
'What the hell's an okta, Murphy?'
'One okta is one eighth of sky area covered, sir. Oktas have replaced the former tenths. No typhoons have been recorded in April for over fifty years and navy int. call typhoons unlikely. Wind is easterly, nine to ten knots but any fleet that runs with it must count on periods of calm, also contrary winds too, sir. Humidity around eighty per cent, temperature fifteen to twenty-four centigrade. Sea conditions calm with a small swell. Currents around Swatow tend to run northeast through the Taiwan Strait, at around three sea miles per day. But further westward — on this side, sir -'
'That's one thing I do know, Murphy,' Martello put in sharply. 'I know where west is, dammit.' Then he grinned at Smiley as if to say 'these young whipper-snappers'.
Murphy was again unmoved. 'We have to be prepared to calculate the speed factor and consequently the progress of the fleet at any one point in its journey, sir.'
'Sure, sure.'
'Moon, sir,' Murphy continued. 'Assuming the fleet to have exited Swatow on the night of Friday April twenty-fifth, the moon would be three days off of full -'
'Why do we assume that, Murphy?'
'Because that's when the fleet exited Swatow, sir. We had confirmation from navy int. one hour ago. Column of junks sighted at the eastern end of fishing bed C and easing westward with the wind, sir. Positive identification of the lead junk confirmed.'
There was a prickly pause. Martello coloured.
'You're a clever boy, Murphy,' Martello said, in a warning tone. 'But you should have given me that information a little earlier.'
'Yes, sir. Assuming also that the intention of the junk containing Nelson Ko is to hit Hong Kong waters on the night of May four, the moon will be in its last quarter, sir. If we follow precedents right down the line -'
'We do,' said Smiley firmly. 'The escape is to be an exact repetition of Drake's own journey in fifty-one.'
Once more, no one doubted him, Guillam noticed. Why not? It was utterly bewildering.
'- then our junk should hit the southernmost out-island of Po Toi at twenty hundred hours tomorrow, and rejoin the fleet up along the Pearl River in time to make Canton harbour between zero ten thirty and twelve hundred hours following day, May five, sir.'
While Murphy droned on, Guillam covertly kept his eye on Smiley, thinking, as he often thought, that he knew him no better today than when he first met him back in the dark days of the cold war in Europe. Where did he slip away to at all odd hours? Mooning about Ann? About Karla? What company did he keep that brought him back to the hotel at four in the morning? Don't tell me George is having a second spring, he thought. Last night at eleven there had been a scream from London, so Guillam had trailed up here to unbutton it. Westerby adrift, they said. They were terrified Ko had had him murdered or, worse, abducted and tortured, and that the operation would abort in consequence. Guillam thought it more likely Jerry was holed up with a couple of air-hostesses somewhere en route to London but with that priority on the signal he had no option but to wake Smiley and tell him. He rang his room and got no answer so he dressed and banged on Smiley's door and finally he was reduced to picking the lock, for now it was Guillam's turn to panic: he thought Smiley might be ill.
But Smiley's room was empty and his bed unslept in, and when Guillam went through his things he was fascinated to see that the old fieldman had gone to the length of sewing false name tapes in his shirts. That was all he discovered, however. So he settled in Smiley's chair and dozed and didn't wake till four when he heard a tiny flutter and opened his eyes to see Smiley stooped and peering at him about six inches away. How he got into the room so silently, God alone knew.
'Gordon?' he asked softly. 'What can I do for you?' for they were on an operational footing, of course, and lived with the assumption the rooms were bugged. For the same reason Guillam did not speak, but handed Smiley the envelope containing Connie's message, which he read and re-read, then burned. Guillam was impressed how seriously he took the news. Even at that hour, he insisted on going straight up to the Consulate to attend to it, so Guillam went along to carry his bags.
'Instructive evening?' he asked lightly, as they plodded the short way up the hill.
'I? Oh, to a point, thank you, to a point.' Smiley replied, doing his disappearing act, and that was all Guillam or anyone could get out of him about his nocturnal or other ambles. Meanwhile, without the smallest explanation of his source, George was bringing in hard operational data in a manner which brooked no enquiry from anyone.
'Ah George, we can count on that, can we?' Martello asked in bewilderment, on the first occasion that this happened.
'What? Oh yes, yes, indeed you may.'
'Great. Great footwork, George. I admire you,' said Martello heartily, after a further puzzled silence, and from then on they had gone along with it, they had no choice. For nobody, not even Martello, quite dared to challenge his authority.
'How many days' fishing is that, Murphy?' Martello was asking.
'Fleet will have had seven days' fishing and hopefully make Canton with full holds, sir.'
'That figure, George?'
'Yes, oh yes, nothing to add, thank you.'
Martello asked what time the fleet would have to leave the fishing beds in order for Nelson's junk to make tomorrow evening's rendezvous on time.
'I have put it at eleven tomorrow morning,' Smiley said, without looking up from his notes.
'Me too,' said Murphy.
'This rogue junk, Murphy,' Martello said, with another deferential glance at Smiley.
'Yes, sir,' said Murphy.
'Can it break away from the pack that easy? What would be its cover for entering Hong Kong waters, Murphy?'
'Happens all the time, sir. Red Chinese junk fleets operate a collective catch system without profit motivation, sir. Consequence of that, you get the single junks that break away at night time and come in without lights and sell their fish to the out-islanders for money.'
'Literally moonlighting!' Martello exclaimed, much amused by the felicity of the expression.
Smiley had turned to the map of Po Toi island on the other wall and was tilting his head in order to intensify the magnification of his spectacles.
'What size of junk are we talking on' Martello asked.
'Twenty-eight man long-liners, sir, baited for shark, golden thread and conger.'
'Did Drake use that type also?'
'Yes,' said Smiley, still watching the map. 'Yes, he did.'
'And she can come that close in, can she? Provided the weather allows?'
Again it was Smiley who answered. Till today, Guillam had not heard him so much as speak of a boat in his life.
'The draw of a long-liner is less than five fathoms,' he remarked. 'She can come in as close as she wishes, provided always that the sea is not too rough.'
From the back bench, Fawn gave an immoderate laugh. Wheeling round in his chair Guillam shot him a foul look. Fawn leered and shook his head, marvelling at his masters' omniscience.
