he had not abandoned the case; that, secretly, he would be
working on it still while----

Her meditations were interrupted by Julius, who adjured her to
"get right in."

"You're looking kind of thoughtful," he remarked as they started
off. "Did the old guy say anything more?"

Tuppence opened her mouth impulsively, and then shut it again.
Sir James's words sounded in her ears: "Never tell all you
know--not even to the person you know best." And like a flash
there came into her mind another memory. Julius before the safe
in the flat, her own question and the pause before his reply,
"Nothing." Was there really nothing? Or had he found something
he wished to keep to himself? If he could make a reservation, so
could she.

"Nothing particular," she replied.

She felt rather than saw Julius throw a sideways glance at her.

"Say, shall we go for a spin in the park?"

"If you like."

For a while they ran on under the trees in silence. It was a
beautiful day. The keen rush through the air brought a new
exhilaration to Tuppence.
