you. I could hardly make out a word he said."

With this Caledonian shaft and a side-glance at Stuart, Inspector
Dunbar sat down at the table.

"Here's Dr. Stuart's description of the missing cabman," he continued,
taking out his note-book. "Dr. Stuart has viewed the body and it is
not the man. You had better take a proper copy of this."

"Then the cabman wasn't Max?" cried Sowerby eagerly. "I thought not."

"I believe you told me so before," said Dunbar sourly. "I also seem to
recall that you thought a scorpion's tail was a Prickly Pear.
However--here, on the page numbered twenty-six, is a description of
the woman known as Mlle. Dorian. It should be a fairly easy matter to
trace the car through the usual channels, and she ought to be easy to
find, too."

He glanced at his watch. Stuart was standing by the lofty window
looking out across the Embankment.

"Ten o'clock," said Dunbar. "The Commissioner will be expecting us."

"I am ready," responded Stuart.

Leaving Sergeant Sowerby seated at the table studying the note-book,
Stuart and Dunbar proceeded to the smoke-laden room of the Assistant
Commissioner. The great man, suavely satanic, greeted Stuart with
that polished courtesy for which he was notable.
