walked back, "we know that Cayley is
perjuring himself and risking himself over this business, and that must
be for one of two reasons. Either to save Mark or to endanger him.
That is to say, he is either whole-heartedly for him or whole-heartedly
against him. Well, now we know that he is against him, definitely
against him."

"But, I say, you know," protested Bill, "one doesn't necessarily try to
ruin one's rival in love."

"Doesn't one?" said Antony, turning to him with a smile.

Bill blushed.

"Well, of course, one never knows, but I mean--"

"You mightn't try to ruin him, Bill, but you wouldn't perjure yourself
in order to get him out of a trouble of his own making."

"Lord! no."

"So that of the two alternatives the other is the more likely."

They had come to the gate into the last field which divided them from
the road, and having gone through it, they turned round and leant
against it, resting for a moment, and looking down at the house which
they had left.

"Jolly little place, isn't it?" said Bill.

"Very. But rather mysterious."

"But what about luggage and tradesmen and that kind of thing?"

"Oh, there's a cart-track, but motor-cars can't come any nearer than the
road" he turned round and pointed "up there. So the week-end millionaire
people don't take it. At least, they'd have to build a road and a garage
and all the rest of it, if they did."

"I see," said Antony carelessly, and they turned round and continued
their walk up to the road. But later on he remembered this casual
conversation at the gate, and saw the importance of it.

CHAPTER XVI. Getting Ready for the Night

What was it which Cayley was going to hide in that pond that night?
Antony thought that he knew now. It was Mark's body.

From the beginning he had seen this answer coming and had drawn back
from it. For, if Mark had been killed, it seemed such a cold-blooded
killing. Was Cayley equal to it? Bill would have said "No," but that was
because he had had breakfast with Cayley, and lunch with him, and dinner
with him; had ragged him and played games with him. Bill would have said
"No," because Bi
