He stooped down and moved forward in the attitude of a Russian
dancer, "And here are the wax matches which the chauffeur struck,"
he counted, "one, two, three, four, five, six, allow three for
each cigarette on a boisterous night like last night, that makes
three cigarettes. Here is a cigarette end, Mansus, Gold Flake
brand," he said, as he examined it carefully, "and a Gold Flake
brand smokes for twelve minutes in normal weather, but about eight
minutes in gusty weather. A car was here for about twenty-four
minutes - what do you think of that, Mansus?"

happens to be the car you're looking for."

"I am looking for any old car," said T. X.

He found no other trace of car wheels though he carefully followed
up the little lane until it reached the main road. After that it
was hopeless to search because rain had fallen in the night and in

London.

"You will go straight to Cadogan Square and arrest the chauffeur
of Mr. Kara," he said.

"Upon what charge!" asked Mansus hurriedly.
