I did not hear young Renauld’s answer, for my attention was distracted by an unusual appearance a little further down the hedge. There appeared to be a brown bush there, which seemed odd, to say the least of it, so early in the summer. I stepped along to investigate, but, at my advance, the brown bush withdrew itself precipitately, and faced me with a finger to its lips. It was Giraud.

Enjoining caution, he led the way round the shed until we were out of ear-shot.

“What were you doing there?” I asked.

“Exactly what you were doing—listening.”

“But I was not there on purpose!”

“Ah!” said Giraud. “I was.”

As always, I admired the man whilst disliking him. He looked me up and down with a sort of contemptuous disfavour.

“You didn’t help matters by butting in. I might have heard something useful in a minute. What have you done with your old fossil?”

“M. Poirot has gone to Paris,” I replied coldly.

“And I can tell you, M. Giraud, that he is anything but an old fossil. He has solved many cases that have completely baffled the English police.”
