Mr. Vincey's first impulse was naturally to join in the pursuit of his friend, in order if possible to save him from the violence of the indignant people. But his action was slow, the blow had half stunned him, and while this was still no more than a resolution came the news, shouted through the crowd, that Mr. Bessel had eluded his pursuers. At first Mr. Vincey could scarcely credit this, but the universality of the report, and presently the dignified return of two futile policemen, convinced him. After some aimless inquiries he returned towards Staple Inn, padding a handkerchief to a now very painful nose.

He was angry and astonished and perplexed. It appeared to him indisputable that Mr. Bessel must have gone violently mad in the midst of his experiment in thought transference, but why that should make him appear with a sad white face in Mr. Vincey's dreams seemed a problem beyond solution. He racked his brains in vain to explain this. It seemed to him at last that not simply Mr. Bessel, but the order of things must be insane. But he could think of nothing to do. He shut himself carefully into his room, lit his fire—it was a gas fire with asbestos bricks—and, fearing fresh dreams if he went to bed, remained bathing his injured face, or holding up books in a vain attempt to read, until dawn. Throughout that vigil he had a curious persuasion that Mr. Bessel was endeavouring to speak to him, but he would not let himself attend to any such belief.

About dawn, his physical fatigue asserted itself, and he went to bed and slept at last in spite of dreaming. He rose late, unrested and anxious, and in considerable facial pain. The morning papers had no news of Mr. Bessel's aberration—it had come too late for them. Mr. Vincey's perplexities, to which the fever of his bruise added fresh irritation, became at last intolerable, and, after a fruitless visit to the Albany, he went down to St. Paul's Churchyard to Mr. Hart, Mr. Bessel's partner, and, so far as Mr. Vincey knew, his nearest friend.

He was surprised to learn that Mr. Hart, although he knew nothing of the outbreak, had also been disturbed by a vision, the very vision that Mr. Vincey had seen—Mr. Bessel, white and dishevelled, pleading earnestly by his gestures for help. That was his impression of the import of his signs. “I was just going to look him up in the Albany when you arrived,” said Mr. Hart. “I was so sure of something being wrong with him.”

As the outcome of their consultation the two gentlemen decided to inquire at Scotland Yard for news of their missing friend. “He is bound to be laid by the heels,” said Mr. Hart. “He can't go on at that pace for long.” But the police authorities had not laid Mr. Bessel by the heels. They confirmed Mr. Vincey's overnight experiences and added fresh circumstances, some of an even graver character than those he knew—a list of smashed glass along the upper half of Tottenham Court Road, an attack upon a policeman in Hampstead Road, and an atrocious assault upon a woman. All these outrages were committed between half-past twelve and a quarter to two in the morning, and between those hours—and, indeed, from the very moment of Mr. Bessel's first rush from his rooms at half-past nine in the evening—they could trace the deepening violence of his fantastic career. For the last hour, at least from before one, that is, until a quarter to two, he had run amuck through London, eluding with amazing agility every effort to stop or capture him.

But after a quarter to two he had vanished. Up to that hour witnesses were multitudinous. Dozens of people had seen him, fled from him or pursued him, and then things suddenly came to an end. At a quarter to two he had been seen running down the Euston Road towards Baker Street, flourishing a can of burning colza oil and jerking splashes of flame therefrom at the windows of the houses he passed. But none of the policemen on Euston Road beyond the Waxwork Exhibition, nor any of those in the side streets down which he must have passed had he left the Euston Road, had seen anything of him. Abruptly he disappeared. Nothing of his subsequent doings came to light in spite of the keenest inquiry.

Here was a fresh astonishment for Mr. Vincey. He had found considerable comfort in Mr. Hart's conviction: “He is bound to be laid by the heels before long,” and in that assurance he had been able to suspend his mental perplexities. But any fresh development seemed destined to add new impossibilities to a pile already heaped beyond the powers of his acceptance. He found himself doubting whether his memory might not have played him some grotesque trick, debating whether any of these things could possibly have happened; and in the afternoon he hunted up Mr. Hart again to share the intolerable weight on his mind. He found Mr. Hart engaged with a well-known private detective, but as that gentleman accomplished nothing in this case, we need not enlarge upon his proceedings.

All that day Mr. Bessel's whereabouts eluded an unceasingly active inquiry, and all that night. And all that day there was a persuasion in the back of Vincey's mind that Mr. Bessel sought his attention, and all through the night Mr. Bessel with a tear-stained face of anguish pursued him through his dreams. And whenever he saw Mr. Bessel in his dreams he also saw a number of other faces, vague but malignant, that seemed to be pursuing Mr. Bessel.

It was on the following day, Sunday, that Mr. Vincey recalled certain remarkable stories of Mrs. Bullock, the medium, who was then attracting attention for the first time in London. He determined to consult her. She was staying at the house of that well-known inquirer, Dr. Wilson Paget, and Mr. Vincey, although he had never met that gentleman before, repaired to him forthwith with the intention of invoking her help. But scarcely had he mentioned the name of Bessel when Doctor Paget interrupted him. “Last night—just at the end,” he said, “we had a communication.”

He left the room, and returned with a slate on which were certain words written in a handwriting, shaky indeed, but indisputably the handwriting of Mr. Bessel!
