“Hold on! There was a Parish Council meetin’ to demand reprisals, of course, an’ there was the policeman an’ me pokin’ about among the ruins till the Explosives Expert came down in his motor car at three P. M. Monday, an’ he meets all the Margetts off their rockers, howlin’ in the surgery, an’ he sees my swim-hole fillin’ up to the brim.”

“What did he say?” Pole inquired.

“He sized it up at once. (He had to get back to dine in town that evening.) He said all the evidence proved that it was a lucky shot on the part of one isolated Hun ’plane goin’ home, an’ we weren’t to take it to heart. I don’t know that anybody but the Margetts did. He said they must have used incendiary bombs of a new type—which he’d suspected for a long time. I don’t think the man was any worse than God intended him to be. I don’t reelly. But the Shropshire Sergeant said——”

“And what did you think?” I interrupted.

“I didn’t think. I knew by then. I’m not a Sherlock Holmes; but havin’ chucked ’em an’ chucked ’em back and kicked ’em out of the light an’ slept with ’em for two years, an’ makin’ my livin’ out of them at that time, I could recognise the fuse of a Mills bomb when I found it. I found all three of ’em. ’Curious about that second in Margetts’ glasshouse. Hickmot mus’ have raked the ashes out of the furnace, popped it in, an’ shut the furnace door. It operated all right. Not one livin’ pane left in the putty, and all the brickwork spread round the yard in streaks. Just like that St. Firmin village we were talking about.”

“But how d’you account for young what’s-his-name gettin’ his arm broken?” said Pole.

“Crutch!” said Bevin. “If you or me had taken on that night’s doin’s, with one leg, we’d have hopped and sweated from one flank to another an’ been caught half-way between. Hickmot didn’t. I’m as sure as I’m sittin’ here that he did his doings quiet and comfortable at his full height—he was over six feet—and no one noticed him. This is the way I see it. He fixed the swim-hole for Mrs. Bevin’s ducks first. We used to talk over our own affairs in front of him, of course, and he knew just what she wanted in the way of a pond. So he went and made it at his leisure. Then he prob’ly went over to Margetts’ and lit the first rick, knowin’ that the wind ’ud do the rest. When young Margetts saw the light of it an’ came out to look, Hickmot would have taken post at the back-door an’ dropped the young swine with his crutch, same as we used to drop Huns comin’ out of a dug-out. You know how they blink at the light? Then he must have walked off an’ opened Margetts’ stable door to save the horses. They’d be more to him than any man’s life. Then he prob’ly chucked one bomb on top o’ Margetts’ roof, havin’ seen that the first rick had caught the second and that the whole house was bound to go. D’you get me?”

“Then why did he waste his bomb on the house?” said Orton. His glass eye seemed as triumphant as his real one.

“For camouflage, of course. He was camouflagin’ an air-raid. When the Margetts piled out of their place into the street, he prob’ly attended to the glasshouse, because that would be Margetts’ chief means o’ business. After that—I think so, because otherwise I don’t see where all those extra cattle came from that we found in the vegetable piece—he must have walked off an’ rounded up all the butcher’s beasts in the next medder, an’ driven ’em there to help the horses. And when he’d finished everything he’d set out to do, I’ll lay my life an’ kit he curled up like a bloomin’ wombat not fifty yards away from the whole flamin’ show—an’ let us run round him. An’ when he’d had his sleep out, he went up to Roehampton Monday mornin’ by some train that he’d decided upon in his own mind weeks an’ weeks before.”

“Did he know all the trains then?” said Pole.
