"You!" he gasped.

"You!" I cried.

Of the two I was the more surprised. For the moment I was incapable of moving.

He did not speak again, nor attempt to get up. Through the front window of the coupé he saw the small crowd of detectives gathering. The light died out of those bright, black eyes. He clapped the back of his hand to his mouth as you have seen women do in moments of despair. The hand dropped nervelessly in his lap. Before my eyes his face turned livid. His body stiffened out in a horrible brief spasm, and he fell over sideways on the seat—dead!

My eyes and Lanman's were glued alike in horror to the corpse. The left hand, a hand too elegant for a man's had now dropped to the floor. A glance at it explained the tragedy. An immense flat emerald on the ring finger was sprung back revealing a tiny cup beneath. The chief and I looked at each other in understanding.

We were recalled to practical matters by the imperious tooting of a horn up the road. One oncoming chauffeur naturally objected to the barricade of automobiles. Lanman and I alike dreaded the irruption of foolish curiosity-seekers. At a word from me he hustled the detectives into their respective cars, and got them straightened out. They were all ordered back to headquarters. All this happened within a few moments. I don't believe any of the detectives realised that the man was dead.

None of the engines had stopped and we quickly had the road clear. Lanman and I thought so much alike in this crisis that it was hardly necessary to talk. We got into the coupé with its ghastly burden and without touching it, sat down on the two little seats facing it. A glance at the police badge was sufficient for the chauffeur.

"Your master has had a stroke," I said to him. "Take us to his home as soon as possible."

Lanman nodded his approval.

When we got Mount's body to his rooms, we sent for his doctor, one of the most famous practitioners in town, also for the commissioner of police and for Mr. Walter Dunsany.
