“That’s correct,” Sir Clinton confirmed. “Let’s see. That’s fourteen altogether. Less two, twelve. Plus you and myself, fourteen. I think we’ll add to our number. Nothing like being on the safe side. Mr. Chacewater’s personally interested in the affair; I think we’ll take him in also. And Mr. Clifton might reasonably claim some share in the business. That makes sixteen. You’re detaching two constables to watch that lakelet. Well, surely fourteen of us ought to be able to pick up the scoundrel without difficulty.”

“You’re sure that he’ll make for the terrace over the pool, sir?”

“Nothing’s sure in this world, Inspector. But I think there’s a fair chance that he’ll make in that direction. And if he doesn’t, why, then, we can run him down wherever he goes.”

“If he goes up there, we’ll have him,” the Inspector affirmed. “There’ll be no amateur bungling this time, like the last affair. I’ll see to that myself. He won’t slip through a constabulary cordon as he did when he’d only a lot of excited youngsters to deal with.”

“I leave that part of the business entirely in your hands, Inspector,” the Chief Constable assured him.

“What I can’t see,” the Inspector continued, with a faint querulousness in his tone, “is why you’re going about the thing in this elaborate way. Why not arrest him straight off and be done with it?”

“Because there’s one little party you’ve omitted to take into your calculations, Inspector—and that’s the jury. Suspicion’s not good enough for us at this stage. Criminal trials aren’t conducted on romantic lines. Everything’s got to be proved up to the hilt. Frankly, in this case, you’ve been scattering your suspicions over a fairly wide field, haven’t you?”

“It’s our business to be suspicious of everybody,” the Inspector pleaded in extenuation.

“Oh, within limits, within limits, Inspector. You started by suspecting Foxton Polegate; then you branched off to Marden; after that you hovered a bit round Maurice Chacewater; and at the end you were hot on Cecil Chacewater’s heels. There’s too much of the smart reader of detective stories about that. He suspects about six of the characters without having any real proof at all; and then when the criminal turns up clearly in the last chapter he says: ‘Well, that fellow was on my list of suspects.’ That style of thing’s no use in real criminal work, where you’ve got to produce evidence and not merely some vague suspicions.”

“You’re a bit hard, sir,” the Inspector protested.
