"But you saw the men?"

"Yes. As I have already told Inspector Warton."

"What brought you here?"

"I followed two of the men from Ealing."

"I know. But for what reason did you follow them?"

"Because I believed that I recognized them."

"But you were mistaken, eh?" asked the fat sergeant as we still stood at the edge of the grave.

"I hardly know," I answered vaguely, "except that a dastardly attempt was made upon my life because I had pried into the men's business."

The sergeant was silent for a few moments, and I had distinct suspicion that, from the expression upon his face, he did not believe me.
