“There’s something we found out in Dublin today that may change everything,” Darcy said. “The murder victim was not really Timothy Roach. He was using a dead man’s passport.”

Lord Kilhenny looked up with interest for the first time. “Then who was he?”

“That’s what we hope the American embassy will find out,” Darcy said. “They’ll be sending pictures of him back to Chicago in hopes that someone there may recognize him. Also his fingerprints, just in case they’re on file.”

“Really?”

I could see a flicker of hope in his eyes.

“It shouldn’t be that hard to trace him,” I said. “How many millionaires can there be in America these days who can afford to pay cash for a castle and a racing stable? The depression hit them harder than us over there, didn’t it?”

“So the question is, who might have wanted him dead and come over here to kill him?” Princess Zamanska leaned forward, waving a red-nailed finger at us. I don’t think she liked being left out of the conversation.

“Do you remember anyone coming from America to visit him recently?” Darcy asked. “Anyone he met who made him uneasy?”

Lord Kilhenny stared into the fire again. A log had just dropped into place, sending up a shower of sparks. “I wasn’t exactly part of his inner circle, you know. He and I hardly exchanged a word. And from my situation here, I couldn’t see anyone coming to the main gate. He might have had any number of visitors, except that his manservant claimed that he had none. And he certainly seldom went out, only in the motorcar or to the race meetings.”

“And he didn’t talk to anybody there?” Darcy asked. “You didn’t see any interactions where he was confrontational or wary?”

Lord Kilhenny shook his head. “He stayed well away from the other owners. Answered in one-syllable words if they approached him. Of course, from what we suspect now, he was betting on his own horses. Now I look back on it, I wonder if he was betting on them to lose sometimes. There were occasions when I could have sworn a horse should have won and it didn’t seem to me that the jockey was urging it on in the final stretch.”

“This shows he had a devious mentality,” Princess Zamanska said, “but it doesn’t seem relevant to his murder. Apart from people who put money on losing horses, there is not one person who would have been angry enough to seek his death.”

“Apart from me,” Lord Kilhenny said. “After the way he treated me, the way he tarnished my reputation like that, I could easily have killed him.”

“But you didn’t,” I said. “And I don’t believe you did this time either. Somebody has cleverly worked to make you look guilty.”
