On that, they exchanged good nights and Forsby left them. Tired after their long day, they fell asleep within a few minutes of getting into bed and did not wake until Harlow called them with cups of tea and told them he would be bringing them breakfast in half an hour.

At half past nine Forsby came along to them with the most welcome news that Khune had spent his first untroubled night for nearly a fortnight and that the tape on the recorder remained completely blank. They then set out in Forsby's car on their reconnaissance.

Between the Station and Lone Tree Hill there lay a stretch of wooded high ground, so they did not come in sight of the hill until they were within a mile of it; but then they could see that on three sides it was surrounded by open moorland. Turning off the main road, Forsby drove across the bridge and some way along the track that skirted the base of the hill till he reached a path that wound up it. Getting out, they walked the half mile to its summit, had a good look round, then made their way through the knee-deep heath and young bracken down to the wood.

By eleven o'clock they were on the way back to the Station and had made their plan. Verney was to lie in wait in the wood, with six of the police, and the remainder were to be posted at intervals in two semi-circles round the hill behind such boulders and gorse bushes as offered the best cover. As it seemed obvious that Lothar must arrive by car and would approach the hill from the road, that segment of the circle was, to begin with, to be left open. But Forsby and Barney were to keep the bridge under observation from the wooded rise between the hill and the Station. When they saw Lothar cross the bridge they were to drive down the road in Forsby's car, get out and, with his two rods, start fishing in the stream. By that time Lothar should be sideways on to them and half way up the hill, so could hardly fail to see them. This stratagem they hoped would serve the dual purpose of cutting off his retreat to the road and inducing him readily to accept Otto's suggestion that, before he handed over the paper, they should move down the far side of the hill into the wood, and so be out of sight of the fishermen.
