"You'll drop me, as usual, at the three roads beyond Mumby. Then go into Skegness and put up for the night. Meet me at the same spot to-morrow morning at seven-thirty." "Very well, sir," was the young man's obedient reply. "Let's see," remarked Rodwell. "When we were up in this lonely, forsaken part of the country a week ago, where did you put up?" "The last time in Louth, sir. The time before in Lincoln, and the time before that in Grimsby. I haven't been in Skegness for a full month." "Then go there, and mind and keep your mouth shut tight!" "I always do, sir." "Yes, it pays you to do so--eh?" laughed Rodwell. "But I confess, Penney, that I'm getting heartily sick of this long journey," he sighed, "compelled, as we are, to constantly go many miles out of our way in order to vary the route." "The road is all right in summer, sir, but it isn't pleasant on a cold stormy night like this--especially when you've got a two-mile walk at the end of it." "That's just it. I hate that walk. It's so dark and lonely, along by that open dyke. Yet it has to be done; and, after all, the darker the night--perhaps the safer it is." Then he lapsed again into silence, while the car--well-driven by Penney, who was an expert driver--flew across the broad open fenlands, in the direction of the sea. The December night was dark, with rain driving against and blurring the windscreen, in which was a small oblong hole in the glass, allowing Penney to see the long, lonely road before him. Passing the station at Horncastle, they continued through the town and then up over the hill on the Spilsby road and over the wide gloomy stretch until, about half-past seven o'clock, after taking a number of intricate turns up unfrequented fen-roads, they found themselves passing through a small, lonely, ill-lit village. Beyond this place, called Orby, they entered another wide stretch of those low-lying marshes which border the North Sea on the Lincolnshire coast, marshes intersected by a veritable maze of roads, most of which were without sign-posts, and where, in the darkness, it was a very easy matter to lose one's way. But Penney--who had left the high road on purpose--had been over those cross-roads on many previous occasions. Indeed, he knew them as well as any Fenman, and without slackening speed or faltering, he at last brought the car to a standstill a few miles beyond the village of Mumby, at a point where three roads met about two miles from the sea. It was still raining--not quite so heavily as before, but sufficiently to cause Rodwell to discard his fur-lined overcoat for a mackintosh. Then, having placed an electric flash-lamp in his pocket, together with a large bulky cartridge envelope, a silver flask and a packet of sandwiches, he took a stout stick from the car and alighting bade the young man good-night, and set forth into the darkness.
