away ticketed in some pigeon-hole in his desk. "Let us see the
garage!"

They followed the road between the bushes until a turn showed them
the garage with its doors open.

"The doors were found unlocked?"

"Just as you see them."

Hanaud nodded. He spoke again to Servettaz. "What did you do with
the key on Tuesday?"

"I gave it to Helene Vauquier, monsieur, after I had locked up the
garage. And she hung it on a nail in the kitchen."

"I see," said Hanaud. "So any one could easily, have found it last
night?"

"Yes, monsieur--if one knew where to look for it."

At the back of the garage a row of petrol-tins stood against the
brick wall.

"Was any petrol taken?" asked Hanaud.

"Yes, monsieur; there was very little petrol in the car when I
went away. More was taken, but it was taken from the middle tins--
these." And he touched the tins.
