Kennedy and I had been interested up to this point. Now we were eager to have him go on. "He died on the voyage up," continued Burke, "just after passing the Gulf Stream, suddenly and from no apparent cause. At least the ship's surgeon couldn't find any cause and neither could they down at Quarantine. So after some time they let the ship proceed up the bay and placed the whole thing in the hands of the Secret Service."
"Is there anyone you suspect?" I asked.
"Suspect?" repeated Burke. "I suspect them all. The Haytien was full of niggers—as superstitious as they make 'em. The ship's surgeon tells me that after the body of Leon was discovered there was such a scene as he had never witnessed. It was more like bedlam than a group of human beings. Some were for putting the body over into the sea immediately. Others threatened murder if it was done. Most of them didn't know what it was they wanted. Then, there was a woman there. She seemed to be nearly crazy—"
There came a knock at the laboratory door.
"If you'll just go into the next room with Walter," said Craig to Burke, "I'll see you in a few minutes. Sit down, make yourself at home."
I went in with him and Burke dropped into a chair beside my typewriter. The laboratory door opened. From where we were sitting we could see in a mirror on the opposite wall that it was a girl, dark of skin, perhaps a mulatto, but extremely beautiful, with great brown eyes and just a trace of kinkiness in her black hair. But it was the worried, almost haunted, look on her face that attracted one's attention most.
I happened to glance at Burke to see whether he had noticed it. I thought his eyes would pop out of his head.
Just then Kennedy walked across the laboratory and closed our door.
"What's the matter?" I whispered.
But before Burke could reply, a draught opened the door just a bit. He placed his finger on his lips. We could not close the door, and we sat there in our corner unintentional but no less interested eavesdroppers.
