Tom's eyes searched the room as though looking for something. Gregg was standing with his back to the fire-place, but noticing that Tom seemed to be trying to look behind him, he moved away. Tom immediately pointed to the clock that stood on the mantelpiece.

"It was a clock," he said, slowly, "just like that one, only more so, in a manner of speaking. I mean it 'ad more 'ands and figures, and they was going round very fast. But it 'ad a glass face just like that one, and it was stuck on 'is 'ead just where the back ought to be. The sun was shining on it at first. That's why I couldn't be sure what it was for a long time. But when I looked closer, I could see plain enough, and it made me feel all wobbly, sir."

"Was there a loud noise?" asked Gregg.

"No, sir, not then. But the 'ands was moving very fast, and there was a sort of 'umming going on like a lot of clocks all going on at once, only quiet like. I was so taken back I didn't know what to do, but presently I caught 'old of 'is legs and tried to pull 'im out. It weren't a easy job, 'cos 'is legs was kicking all the time, and although I 'ollered out to 'im 'e took no notice. At last I dragged 'im out, and 'e lay on the grass, still kicking. 'E never even tried to get up, and at last I took 'old of his shoulders and picked 'im up. And then, as soon as I got 'im up and stood 'im on his feet, and afore I 'ad time to 'ave a good look at 'im, off he goes, like greased lightning. An awful noise started, like machinery, and afore I 'ad time to turn round 'e was down the path towards Bapchurch and out of sight. I tell you, sir, it gave me a proper turn."

"But how did you come by these?" questioned Gregg, who was still holding the hat and wig.

"I see them lying in the pit," explained Tom, "they must 'ave dropped off 'is 'ead as he lay there. Of course, 'e 'adn't fallen very far, otherwise 'is legs wouldn't ave been sticking up. It 'aint very steep just there, and 'is 'ead must 'ave caught in a bit of furze. But the 'at and wig 'ad rolled down to the bottom. After 'e'd gone I climbed down and picked them up."

Gregg passed the hat and wig to Allingham, and whispered something. The other looked at the inside of the hat. There was a small label in the centre, with the following matter printed upon it:—

DUNN BROTHERS.
UNIVERSAL HAT PROVIDERS.
ESTABLISHED OVER 2,000 YEARS.

For a moment Allingham's face was a study in bewilderment. He tried to speak, but only succeeded in producing an absurd snigger. Then he tried to laugh outright, and was forced into rapid speech. "Well, what did I say? The whole thing is preposterous. I'm afraid, inspector, we've troubled you for nothing. The fact is, somebody has been guilty of a monstrous hoax."

"Look at the wig, look at the wig," interrupted Gregg, feverishly.
