On this occasion he began, while they waited for a minute on the edge
of the Strand:

"I hear that Bennett has given up his theory of truth."

Denham returned a suitable answer, and he proceeded to explain how
this decision had been arrived at, and what changes it involved in the
philosophy which they both accepted. Meanwhile Katharine and Rodney
drew further ahead, and Denham kept, if that is the right expression
for an involuntary action, one filament of his mind upon them, while
with the rest of his intelligence he sought to understand what Sandys
was saying.

As they passed through the courts thus talking, Sandys laid the tip of
his stick upon one of the stones forming a time-worn arch, and struck
it meditatively two or three times in order to illustrate something
very obscure about the complex nature of one's apprehension of facts.
During the pause which this necessitated, Katharine and Rodney turned
the corner and disappeared. For a moment Denham stopped involuntarily
in his sentence, and continued it with a sense of having lost
something.

Unconscious that they were observed, Katharine and Rodney had come out
on the Embankment. When they had crossed the road, Rodney slapped his
hand upon the stone parapet above the river and exclaimed:

"I promise I won't say another word about it, Katharine! But do stop a
minute and look at the moon upon the water."

Katharine paused, looked up and down the river, and snuffed the air.
