"Of course I have," came the answer, quickly enough.

"Well, the car mixed up in it is right ahead. There it is, making for Fifth Avenue. Jump in! We'll explain as we go."

The roundsman needed no second invitation. Obviously, unless some brainless young fool was trying to be humorous, there was no time to spare for words. He sprang inside, and Devar cried to the surprised chauffeur:

"Follow that gray auto. Don't kill anybody, but hit up the speed until we are close behind it, and then I'll tell you what next to do."

Little recking what this order really meant, for its true inwardness was hidden at the moment from the ken of those far better versed than he in the tangle of events, Brodie changed gear and touched the accelerator, and the machine whirred past Admiral Farragut's statue at a pace which would have caused even doughty "Old Salamander" to blink with astonishment.

While four pairs of eyes were watching the fast moving vehicle in front, Curtis gave the policeman a brief resume of the night's doings since he and Devar had gone with Steingall to the Police Headquarters. There was no need to say much about the actual crime, because the man had full details, with descriptions of the man-slayers, in his notebook.

He was a shrewd person, too. His name was McCulloch; his father had emigrated from Belfast, and a man of such ancestry seldom takes anything for granted.

"I suppose you are not quite certain, Mr. Curtis, that the chauffeur driving that car ahead is the 'Anatole' concerned in the death of Mr. Hunter?" he asked.

But Curtis was of a cautious temperament, too.

"No," he said, "that is more than I dare state, even if I had an opportunity to look at him closely. As it is, I merely received what I may term 'an impression' of him. That, together with the marked similarity of the car to the one I saw outside the hotel, seems to offer reasonable ground for inquiry at any rate."
