"So I discovered," interjected Mr. Barnes.
"I could get nothing out of the fellow in the cellar. Either he cannot or he will not speak English. So I have merely kept him a prisoner, visiting him at midnight only, to avoid Williams, and giving him rations for another day. Meanwhile, I disguised myself and looked for Palma. I could not find him. I had another card, however, and the time came at last to play it. I deduced from Palma's leaving the hotel on the very day when I took the emerald from the Custom-House, that it was prearranged that his hireling should stick to me until he obtained the gem, and then meet him at some rendezvous, previously appointed. Hearing nothing during the past few days, he has perhaps thought that I had left the city, and that his man was still upon my track. Meanwhile I was perfecting my grand _coup_. With the aid of a physician, who is a confidential friend, I obtained a corpse from one of the hospitals, a man about my size, whose face we battered beyond description. We dressed him in my clothing, and fixed the dagger which I had taken from my would-be assassin so tightly in the backbone that it would not drop out. Then one night we took our dummy to the river and securely anchored it in the water. Last night I simply cut it loose and let it drift down the river."
"You knew of course that it would be taken to the Morgue," said Mr. Barnes.
"Precisely. Then I dressed myself as a blind beggar, posted myself in front of the Morgue, and waited."
"You were the beggar?" ejaculated the detective.
"Yes. I have your quarter, and shall prize it as a souvenir. Indeed, I made nearly four dollars during the day. Begging seems to be lucrative. After the newspapers got on the street with the account of my death, I looked for developments. Palma came in due time, and went in. I presume that he saw the dagger, which was placed there for his special benefit, as well as the empty jewel-case, and at once concluded that his man had stolen the gem and meant to keep it for himself. Under these circumstances he would naturally be angry, and therefore less cautious and more easily shadowed. Before he came out, you turned up and stupidly brought a cab, which allowed my man to get a start of me. However, I am a good runner, and as he only rode as far as Third Avenue, and then took the elevated railroad, I easily followed him to his lair. Now I will explain to you what I wish you to do, if I may count on you?"
