Crysteel and Danstor looked at each other in dismay. This was a completely unexpected snag, for the only written characters they had ever seen were television programme announcements, and they had never fully deciphered those. But Danstor, who had an almost photographic memory, rose to the occasion. Holding the chalk very awkwardly, he wrote a sentence which, he had reason to believe, was in common use during such breakdowns in communication.

As her mysterious visitors walked sadly away, old Mrs Tomkins stared in hauled bewilderment at the marks on her slate. It was some time before she deciphered the characters—Danstor had made several mistakes—and even then she was little the wiser.

TRANSMISSIONS WILL BE RESUMED AS SOON AS POSSIBLE.

It was the best that Danstor could do; but the old lady never did get to the bottom of it.

They were little luckier at the next house they tried. The door was answered by a young lady whose vocabulary consisted largely of giggles, and who eventually broke down completely and slammed the door in their faces. As they listened to the muffled, hysterical laughter, Crysteel and Danstor began to suspect, with sinking hearts, that their disguise as normal human beings was not as effective as they had intended.

At Number 3, on the other hand, Mrs Smith was only too willing to talk—at 120 words to the minute in an accent as impenetrable as Sam Higginsbotham’s. Danstor made his apologies as soon as he could get a word in edgeways, and moved on.

“Doesn’t anyone talk as they do on the radio?” he lamented. “How do they understand their own programmes if they all speak like this?”

“I think we must have landed in the wrong place,” said Crysteel, even his optimism beginning to fail. It sagged still further when he had been mistaken, in swift succession, for a Gallup Poll investigator, the prospective Conservative candidate, a vacuum-cleaner salesman, and a dealer from the local black market.

At the sixth or seventh attempt they ran out of housewives. The door was opened by a gangling youth who clutched in one clammy paw an object which at once hypnotized the visitors. It was a magazine whose cover displayed a giant rocket climbing upward from a crater-studded planet which, whatever it might be, was obviously not the Earth. Across the background were the words: “Staggering Stories of Pseudo-Science. Price 25 cents.”

Crysteel looked at Danstor with a “Do you think what I think?” expression which the other returned. Here at last, surely, was someone who could understand them. His spirits mounting, Danstor addressed the youngster.
