She sat, but on about a third of the chair seat.
"My name," I said, "is Archie Goodwin. I'm a private detective, and I work for Nero Wolfe, also a private detec-"
"Nero Wolfe!"
"Right. It will please him to know that you had heard of him, and I'll be sure to tell him. He has been hired by a man named Wellman to find out who murdered his daughter. And another girl has been murdered, one named Rachel Abrams. Also, before that, your brother was murdered. We have reason to believe that the same person committed all three murders. It's a long and complicated reason, and I'll skip it. K you want the details later you can have them. I'll just say that our theory is that your brother was killed because he wrote that novel, Joan Wellman was killed because she had read it, and Rachel Abrams was killed because she had ' typed it."
"The novel-Len wrote?"
"Yes. Don't ask me what was in it, because we don't know. If we did, I wouldn't have had to come out here to see you. I came to get you to help us catch a man that murdered three people, and one of them was your brother."
"But I can't-" She gulped. "How can I help?"
"I'm telling you. I could have tricked you into helping. I've just proved it. You would have come along for a chance at fifty thousand dollars, you know darned well you would. You'd have let me go through your brother's letters for evidence, and whether we found it or not you'd have written the letter to the law firm. That's all I'm asking you to do, only now I'm giving it to you straight and asking you to do it not for a pile of dough but to help catch the man that killed your brother. If you would have done it for money, and you would, don't you think you ought to do it to bring a murderer to justice?"
She was frowning, concentrating. "But I don't see-You only want me to write a letter?"
"That's right. It's like this. We think your brother wrote that novel, and it was a vital element in the murders. We think that someone in that law office is involved and either committed the murders or knows who did. We think that someone is desperately determined that the contents of that manuscript shall not be known to any living person. If we're right, and you send the kind of letter I described, he'll have to move and move quick, and that's all we need, to start him moving. If we're wrong, your sending the letter will do nobody any harm."
She was keeping the frown. "What did you say you wanted me to say in the letter?"
