There had been five such cars seen on the Folkestone⁠—Rye road. One constable reported that a shepherd on the Romney Marshes had told him of a big car⁠—which the police officer believed might have been a Rolls Royce⁠—seen twice on a derelict stretch of road leading into the marshland.

Labar bent his mind to this point. It seemed the most promising of all to start from, although it might, as so often happens in these cases where a man is acting more or less on guess work, prove nothing but a mare’s nest. But if a man wanted to keep out of the way what better place of refuge could he find than these same desolate Romney Marshes.

With Myson in charge at Grape Street, other ends of the investigation in London could for the while be left to themselves. Labar decided that with two men he could rake the district as effectively and more quietly than if he had a dozen. If his guess was right, it would not do to disturb Larry.
