"I'll have to, that's all."

They walked across the lawn and out along the dark drive in silence. Where the ride crossed at the carrefour they halted. There was a dilapidated shrine there to Our Lady of Lesse. They seated themselves on the stone base.

"Harry," said Guild, "how long do you intend to follow me about in this absurd way?"

"I'd like to see you safe across the Dutch frontier."

"Thanks," said Guild drily.

"Don't mention it. I really can reconcile myself to your having your bally head knocked off in uniform, but this sort of thing seems rather ghastly."

"It is. Won't you go on to Quellenheim to oblige me?"

"I'll wait till tomorrow morning," replied Darrel pleasantly.

Guild was silent. They sat there for an hour or more scarcely exchanging a word. Then somebody whistled, cautiously, very near them, and another carefully modulated whistle answered.

"Who goes there!" came a challenging voice.
