"Oh, John!" said Sara, in an agony lest her long-cherished dream of nonchalantly handing over a bunch of crooks to Scotland Yard was to be denied fulfilment by over-caution on John's part. "Of course we know they're crooks, and the book will prove it, somehow. And look - if we don't lay too false a trail, just enough to give us sufficient start to collect the evidence in Rhöndorf, then we could have them arrested when they make up on us!"
"I'm having no dealings with foreign policemen if I can help it," said John, with a firmness which brooked no argument. "With the language difficulties and so on, you never know where you'll land."
