There the narrative found upon Mr. Elvesham’s desk ends. His dead body lay between the desk and the chair. The latter had been pushed back, probably by his last convulsions. The story was written in pencil, and in a crazy hand, quite unlike his usual minute characters. There remain only two curious facts to record. Indisputably there was some connection between Eden and Elvesham, since the whole of Elvesham’s property was bequeathed to the young man. But he never inherited. When Elvesham committed suicide, Eden was, strangely enough, already dead. Twenty-four hours before, he had been knocked down by a cab and killed instantly, at the crowded crossing at the intersection of Gower Street and Euston Road. So that the only human being who could have thrown light upon this fantastic narrative is beyond the reach of questions. Without further comment I leave this extraordinary matter to the reader’s individual judgment. THE STOLEN BACILLUS “This again,” said the Bacteriologist, slipping a glass slide under the microscope, “is a preparation of the celebrated Bacillus of cholera—the cholera germ.” The pale-faced man peered down the microscope. He was evidently not accustomed to that kind of thing, and held a limp white hand over his disengaged eye. “I see very little,” he said. “Touch this screw,” said the Bacteriologist; “perhaps the microscope is out of focus for you. Eyes vary so much. Just the fraction of a turn this way or that.” “Ah! now I see,” said the visitor. “Not so very much to see, after all. Little streaks and shreds of pink. And yet those little particles, those mere atomies, might multiply and devastate a city! Wonderful!” He stood up, and releasing the glass slip from the microscope, held it in his hand towards the window. “Scarcely visible,” he said, scrutinising the preparation. He hesitated. “Are these—alive? Are they dangerous now?” “Those have been stained and killed,” said the Bacteriologist. “I wish, for my own part, we could kill and stain every one of them in the universe.” “I suppose,” the pale man said with a slight smile, “that you scarcely care to have such things about you in the living—in the active state?” “On the contrary, we are obliged to,” said the Bacteriologist. “Here, for instance—” He walked across the room and took up one of several sealed tubes. “Here is the living thing. This is a cultivation of the actual living disease bacteria.” He hesitated. “Bottled cholera, so to speak.”
