Pumphrey’s cheek twitched with disapproval of the provincial policeman’s obtuseness. “It simply means that, security-wise...” He stopped and turned his eyes, like those of an El Greco Christ, upon Ross.
Ross smiled patiently. “Thimble Bay. Let’s start from there, shall we? I don’t have to tell you about the Thimble Bay Establishment. Couldn’t, anyway—not above Sensitivity Three, and you wouldn’t be much wiser if I did. But you’ll understand the place is very much our pigeon. Hence Hopjoy. Among others, naturally.”
“That much I had gathered,” Purbright said. “Of course, Thimble Bay is not usually considered to be in this locality, sir.”
“Really?” Ross sounded surprised. He glanced across at the Chief Constable, as a misled traveller might appeal direct to the king of the country whose inhabitants have proved wayward. “How far, Mr Chubb, would you say Thimble Bay is from here?”
The Chief Constable diffidently waved one of his fine flexible, hands. “I really can’t tell you. Mr Purbright will know.”
“Twenty-seven miles, sir.”
A little puff of disparagement issued from Pumphrey’s black, up-tilted nostrils. “Well, that may seem a long way to you, inspector, but, good heavens, globe-wise...”
“My colleague,” Ross broke in, “doesn’t mean to sound like an astronomer. We do appreciate that you have quite enough on your plate without worrying about what goes on a couple of counties away. It’s just that we have to take rather long views in our job.” He gave a sudden placatory grin and drew a cigarette case from an inner pocket. “Tell me, do you find time to play cricket, inspector?”
“No, sir,” replied Purbright, no less pleasantly.
For a fraction of a second the pressure of Ross’s thumb on the catch of the cigarette case was arrested. Then he completed the movement and offered a cigarette first to Mr Chubb, who pursed his lips in refusal, and then to Purbright. Pumphrey seemed not to qualify.
“The reason I ask,” Ross went on, “is this. Picture Thimble Bay as the wicket. Security is simply a matter of placing fielders. You know, slips, cover-point, silly mid-off, square check...”
“I don’t play lacrosse either, sir,” murmured Purbright.
“Square check,” repeated Ross. “Wrong game. Yes, you’re perfectly right. Full marks.” He leaned back in his chair, crossing his legs. “But you’ve caught on, haven’t you, to what I mean about fielding. Hopjoy—we’ll call him that—was our Flaxborough long-stop, so to speak.”
Purbright digested the metaphor, with which Ross was looking very satisfied. “His job, then, was to intercept such information as happened to leak in this direction.” He turned to the Chief Constable. “I had no idea we were on a spying route; had you, sir?”
“Certainly not,” said Mr Chubb. “This isn’t...”—he sought a sufficiently preposterous location—“Algiers or...or Dublin.”
Ross carefully tapped the ash from his cigarette. “You know Dublin, Mr Chubb?” he inquired of the ashtray.
“I can’t say that I do. Why?”
“The name seemed to occur to you.”
“Oh, that. Well. Roger Casement and everything...association of ideas, I suppose.” To his bewilderment Mr Chubb found himself thinking defensively. He closed his mouth firmly and glanced up at the office clock.
Pumphrey seemed about to slip in a supplementary question but Ross, suddenly benign, reached over and took from his lap the briefcase he had been nursing. “This,” he explained to Purbright, “is pretty sensitive stuff. You’ll appreciate that I can’t let you right into the picture, but these reports from Hopjoy do suggest that he might have been on to something.”
He took from his pocket a number of coins and selected what appeared to be an ordinary florin. “Special knurling,” he observed, indicating the coin’s rim. Then he slipped it into a slot in the otherwise featureless lock of the case and turned it carefully. Purbright guessed that the fine-toothed rim was engaging a tiny gear within the lock. After a second or two there was a click and the flap of the case hung open.
Ross drew out a slim sheaf of papers and began glancing through them without disturbing their order. Purbright caught sight of a couple of maps and a number of smaller sheets that appeared to be accounts. The rest of the papers bore closely-spaced typing, neatly indented and with underlined sub-headings. “Most meticulous chap,” Ross murmured.
The Chief Constable shifted his position slightly and rubbed his chin with two fingers. “We realize,” he said, “that Mr Hopjoy was engaged on somewhat delicate work involving matters that do not concern us as ordinary policemen. What does concern us, though, is the probability of a crime having been committed. Let me be quite frank, gentlemen: to what extent are we going to be able to collaborate in sorting this business out?”
Ross looked a little surprised. “Fully I trust, Mr Chubb. That is why Mr Pumphrey and I are here—to be kept informed with the least inconvenience to you.”
It was Chubb’s turn to raise his brows. “I had hoped for something rather more reciprocal, Mr Ross.” He looked meaningfully at the Hopjoy file. “If it turns out that your man was done away with, the answer might very well lie there.”
“That’s true.” There was a note of doubt in Ross’s voice. “The trouble is that this stuff hasn’t been processed thoroughly yet. Our people gave it a preliminary feed through R Section but the report wasn’t terribly suggestive. All Hopjoy’s leads are green. Linkage negative. Well...” He shrugged and gave Pumphrey a glance that invited confirmation of their difficulties. Pumphrey responded with a judicial nod.
The inspector, who had been listening with polite attention, asked: “What are green leads, Mr Ross?”
“And negative linkages?” threw in Chubb, without sounding in the least curious.
Ross beamed. The sudden smile invested his large, rather lumpishly cast face with a charm that was the greater for being unexpected, like greenery on a pit heap. “I’m sorry about the technicalities,” he said. “A green lead is what you might call a new suspect, someone with no history of unreliability.”
