er four o'clock tomorrow
afternoon."

"At any rate," said Walter, "I think we may be sure of one thing--after
four o'clock tomorrow afternoon you will know all--all." He paused and
repeated, slightly varying the phrase: "Yes, after four o'clock tomorrow
afternoon you will know everything--everything." He added in a brisker
tone: "There's nothing else to arrange?"

"No," said Dunn, "I don't think so, and I had better go now or Deede
Dawson will be suspecting something. He'll want to know what I've been
stopping out so late for. Good-bye, old chap, and good luck."

They shook hands.

"Good-bye and good luck, Rupert, old man," Walter said. "You may depend
on me--you know that."

"Yes, I do know that," Dunn answered.

They shook hands again, and Dunn said: "You've hurt your hand. It's tied
up. Is it anything much?"

"No, no," answered Walter with a little laugh. "A mere scratch. I
scratched it on a bit of wood, a lid that didn't fit properly."

"Well, good-bye and good luck," Dunn said again, and they parted, Walter

Deede Dawson heard him enter, and he came to the door of the room in

You've been a long time."

"I've been thinking," Dunn muttered in the heavy, sulky manner he always

"No," answered Dunn. "I'm not."

"Good," Deede Dawson exclaimed. "There's a lot to win, and no fear of
failure. I don't see that failure's possible. Do you?"

"No," answered Dunn. "I suppose not."

"The mate's sure this time," Deede Dawson declared. "It's our turn to
move, and whatever reply the other side makes, we're sure of our mate
next move. By the way, did you ever solve that problem I showed you the
other day?"

"Yes, I think so," answered Dunn. "It was a long time before I could hit
on the right move, but I managed it at last, I think."

"Come and show me, then," said Deede Dawson, bustling back into his room
and beginning to set up the pieces on his travelling chess-board. "This
was the position, wasn't it? Now, what's your move?"

Dunn showed him, and Deede Dawson burst into a laugh that had in it for
once a touch of honest enjoyment.

"Yes, that would do it, but for one thing you haven't noticed," he said.
"Black can push the pawn at KB7 and make it, not a queen, but a knight,
