en in his family for twenty years. Mrs. Curtis wanted her brother
to marry Miss West."

"Do you think he did marry her?" I could not keep the excitement out of
my voice.

"No. There were reasons"--she stopped abruptly.

"Do you know anything of the family? Are they--were they New Yorkers?"

"They came from somewhere in the south. I have heard Mrs. Curtis say her
mother was a Cuban. I don't know much about them, but Mr. Sullivan had
a wicked temper, though he didn't look it. Folks say big, light-haired
people are easy going, but I don't believe it, sir."

"How long was Miss West here?"

"Two weeks."

I hesitated about further questioning. Critical as my position was, I
could not pry deeper into Alison West's affairs. If she had got into the
hands of adventurers, as Sullivan and his sister appeared to have been,
she was safely away from them again. But something of the situation
in the car Ontario was forming itself in my mind: the incident at the
farmhouse lacked only motive to be complete. Was Sullivan, after all, a

Instead--"She escaped with some bruises," I said.

She glanced at my arm. "You were on the train?"

She waited for more questions, but none coming, she went to the door.
Then she closed it softly and came back.

"Mrs. Curtis is dead? You are sure of it?" she asked.

"She was killed instantly, I believe. The body was not recovered. But I
have reasons for believing that Mr. Sullivan is living."

"I knew it," she said. "I--I think he was here the night before last.
That is why I went to the tower room. I believe he would kill me if
he could." As nearly as her round and comely face could express
it, Jennie's expression was tragic at that moment. I made a quick
resolution, and acted on it at once.

"You are not entirely frank with me, Jennie," I protested. "And I am
going to tell you more than I have. We are talking at cross purposes."

"I was on the wrecked train, in the same car with Mrs. Curtis, Miss West
and Mr. Sullivan. During the night there was a crime committed in that
car and Mr. Sullivan disappeared. But he left behind him a chain of
circumstantial evidence that involved me completely, so that I may
