“To whom?”

“I don’t know; it is not addressed. I’ll show it to you.”

Nick produced the dead girl’s pocketbook,[{41}] from which he took a typewritten slip, on which was this message:

“You failed to keep your engagement last night. I’ll give you just one more chance. Meet me to-night at the same place, 8:30 sharp, and be ready to come to some definite understanding with me. If you fail me this time I will consider myself absolved from my oath.”

“Nick, this is the key to the whole tragedy.”

“I think so, too.”

“The note was never delivered.”

“Certainly not.”

“Why?”

“For want of an opportunity—that’s clear.”
