“It’s a bit hard for me to believe that you can build interstellar spaceships, but can’t get out of a miserable village police station.”

Danstor looked at Crysteel, who shuffled uncomfortably.

“We could get out easily enough,” said the anthropologist. “But we don’t want to use violent means unless it’s absolutely essential. You’ve no idea of the trouble it causes, and the reports we might have to fill in. Besides, if we do get out, I suppose your Flying Squad would catch us before we got back to the ship.”

“Not in Little Milton,” grinned Graham. “Especially if we could get across to the ‘White Hart’ without being stopped. My car is over there.”

“Oh,” said Danstor, his spirits suddenly reviving. He turned to his companion and a lively discussion followed. Then, very gingerly, he produced a small black cylinder from an inner pocket, handling it with much the same confidence as a nervous spinster holding a loaded gun for the first time. Simultaneously, Crysteel retired with some speed to the far corner of the cell.

It was at this precise moment that Graham knew, with a sudden icy certainty, that he was stone-sober and that the story he had been listening to was nothing less than the truth.

There was no fuss or bother, no flurry of electric sparks or coloured rays—but a section of the wall three feet across dissolved quietly and collapsed into a little pyramid of sand. The sunlight came streaming into the cell as, with a great sigh of relief, Danstor put his mysterious weapon away.

“Well, come on,” he urged Graham. “We’re waiting for you.”

There were no signs of pursuit, for P.C. Hinks was still arguing on the phone, and it would be some minutes yet before that bright young man returned to the cells and received the biggest shock of his official career. No one at the “White Hart” was particularly surprised to see Graham again; they all knew where and how he had spent the night, and expressed hope that the local Bench would deal leniently with him when his case came up.

With grave misgivings, Crysteel and Danstor climbed into the back of the incredibly ramshackle Bentley which Graham affectionately addressed as “Rose”. But there was nothing wrong with the engine under the rusty bonnet, and soon they were roaring out of Little Milton at fifty miles an hour. It was a striking demonstration of the relativity of speed, for Crysteel and Danstor, who had spent the last few years travelling tranquilly through space at several million miles a second, had never been so scared in their lives. When Crysteel had recovered his breath he pulled out his little portable transmitter and called the ship.
