"Where are you to be found?" the inspector asked.

"At the Hotel Savoy." He yawned. "I am very sleepy," he complained. "If you will finish with Mr. Tranter as soon as possible, he will take me back in his car."

He turned to the door.

"Stay," said the inspector.

He stopped.

"You have not lost your old fantastic kink," said the inspector, with a faint smile. "The last time we ran together you were five minutes ahead of me at the finish. This time—we will see who is the first to pass the post."

"My friend," said Monsieur Dupont, "I will do my best to give you a good race."

He passed out of the room. The inspector followed him to the door, and called for Mr. Tranter.
