There was a grinding and clashing in the receivers. Then a new voice, harsh and strained with excitement, almost burst their eardrums. "Beware! Beware!" it screamed. "Do not trust him. He is a devil and has put the world asleep. His mind is rotten with hashish. He is a demon from--" Then came a dull, crunching sound. The voice screamed and died away. In the darkened laboratory the faces of the three listeners stood out like ovals of white cardboard. "What do you make of that?" stammered Baron at last. "It looks as if the only persons alive, in New York at least, are hashish addicts--the most debased and murderous of drug fiends." The doctor stopped, his eyes dilating with horror. June crept close to him and threw an arm around his shaking shoulders. "Can't you see? Their time-sense expanded too. Like us they were unaffected. But unlike us they use the pure drug. Hashish smokers are without exception homicidal maniacs, vicious criminals. God!" "Are they responsible for the end of time?" queried Jack. "I don't know. Perhaps some master mind among them is back of it--some engineering wizard who has succumbed to the drug so recently, or who has such a strong constitution that his intelligence has not been destroyed." The little doctor dragged off his headset, disarranging his sparse gray hair. His face was tired and worn but his jaw thrust forward pugnaciously. "We're making headway," he cried. "We know the probable author of the catastrophe is a drug addict and that he is located nearby. We know he has no scruples, for the man who warned us undoubtedly was killed. And I'm convinced those extremely short wave bands hold the secret. Let's knock off for the day. We look like ghosts. To-morrow morning you and June get what equipment you need from across the river. I'll stay here on guard. You'd better raid a drug-store and get some more of our life-saver, too. It's listed under Cannabis Indica." * * * * * The next morning dawned clear and cold. It was early October and there was a chill in the apartment. Baron swung his legs over the edge of the davenport in the living room and stared out at the frost-covered trees of Central Park. The leaves were falling before the brisk wind and forming little eddying mounds over the forms of those lying about the streets. Jack shivered at the thought of the millions and millions of victims of the disaster who littered the Earth. They seemed to accuse him of still being alive. Well, if Manthis was right, perhaps all could be revived before winter set in. June was singing as he and the doctor came to breakfast. Apparently she wished to forget the events of the previous night, so they laughed and joked as though they intended to go on a picnic rather than across a dead city.
