“When all those blunderbusses get through with their heavy work, Norrie, we’ll have a run in with the maid,” said he. “I seem to be the last man on the job. Meantime find out for me how many red-haired people there are about this house or among the immediate circle of the girl’s friends. It is a matter of some importance, because—” he carefully opened the pocketbook, extracted the folded piece of note paper, and, first assuring himself that no one was about, pointed—“because here are two broken, half-inch bits of red hair that I take it are going to play an important part in this case. Remember the Deveraux case? These were wedged back of the cameo on her bracelet, and they got there in her last struggle with whoever shot her. For the time being at least, then, we will eliminate all but red-haired people.”

“Maybe it’s a dog’s hair,” I suggested hopefully.

Lanagan was on the point of retorting with his finished sarcasm when the Hemingway limousine, evidently bringing other members of the family or relations summoned by word of the mournful occurrence, rolled up to the brilliantly lighted porte-cochère. Lanagan’s eye had travelled swiftly and fixed upon some object of interest. I followed his intense gaze.

The chauffeur’s hair was as flaming as a firebrand.

Lanagan’s eyes seemed to be boring straight through the man as the machine came to a stop almost where we sat. The chauffeur’s face was pale, extraordinarily pale, it appeared to me; as he stopped his machine and shut down the gears, there was a perceptible evidence of nervousness in his manner that was possibly entirely natural in view of the shocking happening of a few hours before that had taken the life of his young mistress.

Simultaneously our eyes rested on his uncovered hair.

His hair, if anything, was a shade more auburn than that of the chauffeur! His swollen eyes and pale face were natural under the circumstances, with his marriage hopes thus painfully blasted. They walked within, and Lanagan said:

“Come on. We’ll get first crack at this fellow anyhow. Let’s meet him back at the garage in the rear.”

We had started to walk back to the garage as the chauffeur cranked his machine when from the same low window Leslie and Brady stepped alertly. Leslie held up his hand to the chauffeur. The two officers were beside him in a moment. I knew what was coming even before they laid a hand on him. I had seen too many arrests made not to know what was meant by that brusque, cool manner, that quick step, that wary eye even before there came that familiar terse, short snap of the professional thief-taker:
