"Because," said Halkett, coolly, "if I'm knocked on the head and that envelope is found in my clothing and is stolen, the loss of my life would be the lesser loss to my friends."
"Is anybody trying to kill you?"
Halkett shrugged his shoulders; but there seemed to be neither swagger nor bravado in his careless gesture of assent. He said:
"Listen; here's my case in brief. I saw you in the crowd yonder, and I made up my mind concerning you. I have to think quickly sometimes; I took a good look at you and—" He waved one hand. "You look like a soldier. I don't know whether you are or not. But I am ready to trust you. That's all."
"Do you mean to say that you are in any real personal danger?"
"Yes. But that doesn't count. I can look out for myself. What worries me is this envelope. Couldn't you take charge of it? I'd be very grateful."
"How long do you expect me to carry it about?"
"I don't know. I don't know whether anything is likely to happen to me today in this town—or tomorrow on the train—or in Paris—I have no means of knowing. I merely want to get to Paris, if I can, and send a friend back here for that envelope."
"I thought you were to return for it yourself."
"Maybe. Maybe I'll send you a letter by a friend—just a line for him to give you, saying it's all right."
