“Opens the inner sight,” he whispered darkly. “Makes you sensitive to thoughts and thoughtforces.” He paused a moment, staring hard into the other’s eyes. “For instance,” he added slowly, earnestly, “if somebody’s thinking hard about you, I should twig it. See? I should see the thought-stream getting at you—influencing you—making you do this and that. The air is full of loose and wandering thoughts from other minds. I should see these thoughts hovering about your mind like flies trying to settle. Understand? The cause of a sudden change of mood in a man, an inspiration, a helping thought—a temptation——!”

“Bosh!”

“Are you afraid?”

“No. But it’s a poisonous doctrine—that such experiments are worth while even if—if——”

But O’Malley knew his pal.... They took the prescribed dose together, laughing, scoffing, hoping. Then they went out to dine. “We must eat very little,” explained the Irishman. “The stomach must be comparatively empty. And drink nothing at all.”

“What a bore!” said Jones, who was always hungry, and usually thirsty. The prescribed hour passed between the taking of the dose and dinner. They felt nothing more than what Jones described as a “beastly uncomfortable sort of inner heat.”

Opposite them, at a table alone, sat a small man, over-dressed according to their standards, and wearing diamond rings. His face had a curious mixture of refinement and wickedness—like a man naturally sensitive whom circumstances, indulgence, or some special temptation had led astray. He did not notice their somewhat close attention because, in his turn, he was closely watching—somebody else. He ate and drank soberly, but drew his dinner out. The “somebody else” he watched, obviously enough, was a country couple, up probably for the festivities due to the presence of a foreign Potentate in town. They were bewildered by big London. They carried hand-bags. From time to time the old man fingered his breast-pocket. He looked about him nervously. The be-ringed man was kind to them, lent them his newspaper, passed the salt, gave them scraps of favoured, kind, and sympathetic conversation. He was very gentle with them.

“Feel anything yet?” asked O’Malley for the tenth time, noticing a curious, passing look on his companion’s face. “I don’t feel a blessed thing meself! I believe that chemist fooled me, gave me diluted stuff or something——” He stopped short, caught by the other’s eye. They had been dining very sparingly, much to the disgust of the waiter, who wanted their table for more remunerative customers.

“I do feel something, yes,” was the quiet reply. “Or, rather, I see something. It’s odd; but I really do——”

“What? Out with it! Tell me!”
