"I think the local police are blundering the whole of this affair," Rayner went on. "Yet I can't make out by what means I was so suddenly put out of action. That curious, strong smell of almonds puzzles me. It's in my nostrils now."

"Your fancy, I expect," I said.

At that moment came a knock at the door, and the tall young constable entered, the same man who had been on duty when I had gone up to inspect the seat where Craig's body had been found.

"The Inspector has sent me, sir," he exclaimed, saluting, "to say he'd like to see you at once. He's just along the West Cliff—at Beacon House, where Mr. Craig lived in."

"Certainly," I replied. "Tell him I will come at once."

The constable disappeared, and turning to Rayner, I said: "I wonder why Treeton wishes to see me in such a hurry? What has happened now?" Then, promising to return quickly, I went out.

At Beacon House, I found Treeton standing in the front sitting-room, on the ground-floor, talking seriously with the landlady.

"Hulloa! Mr. Vidal," he exclaimed as I entered. "Something more has occurred in this house during the night. The place has been broken into by burglars, who've got clean away with all old Mr. Gregory's collection of jewellery."

"Burglary," I repeated slowly; and then all that Rayner had told me flashed across my mind. I saw the reason for Jeanjean and his mysterious cyclist companion being near the house, and also why Rayner, on being detected, had been rendered senseless.
