Again, think of the site of a London theatre! Prehistoric man or beast may well lie buried there; witches accused of practising their nefarious rites on or near that site may well have been burnt there.

Think, too, of the houses that once may have stood there! Inns, with dark tell-tale stains on their boards; taverns, tainted with vice—the rendezvous of truculent swashbucklers and painted jades; and even more terrible still, cruel and ghastly slaughter-houses.

Ground, then, and houses alike, all may have had their hauntings; and the ghosts may have stayed on, as ghosts often do, haunting anew each successive building. Yes, more than one London theatre is haunted—and several of these theatres have more than one ghost.

The proprietors affect ignorance and of course tell you nothing. They like to see long queues of people waiting for admission to their show, but they have no desire to see a corresponding crowd at the box office seeking permission to sit up all night in the theatre to see the ghost. No, if you want to find out if a theatre is haunted, you must not apply to the proprietor, you must inquire of the actors themselves; and, in order to stand a really good chance of discovering the truth, you should, if possible, for a time become one of them. It was for the purpose of making such a discovery that I took it into my head one day last year to apply for a walk on at the Mercury. I had often wondered if the Mercury was haunted. I speedily found out that it was not. Still, I was not altogether disappointed, for I learned from some of my fellow-walkers on and from one of the stage hands of several very interesting cases of hauntings at other of the London theatres. There is the Prince Regent’s, for instance, which, as recently as the late nineties had a dressing-room, 25, that was always kept locked. It was in the autumn of 1897 that John W. Mayhewe was engaged to play a small but rather important part there in The Merciful Pirate. The cast was an unusually large one, and Mayhewe discovered that he had to share dressing-room 25 with another actor called Talbotson. The opening night of the play, however, Talbotson was laid up with influenza, and Mayhewe had room 25 to himself. Being one of those over-anxious people who err on the side of being ultra-punctual, he arrived at the theatre at least an hour before the curtain went up, and, on the way to his room, he paused to chat with the stage doorkeeper.

“I noticed,” he remarked, “when I was dressing for rehearsal yesterday that my room smelt very musty. Isn’t it often used?”

“It hasn’t been used since I’ve been here,” was the reply.

“Why?” said Mayhewe.

“I can’t tell you,” the doorkeeper answered surlily. “If you want to know, you had better ask the stage manager.”

Not caring to do this, Mayhewe made no further remarks, but hastened upstairs. No one was about, and the noise of his footsteps sounded strangely loud in the silent emptiness of the passages. He entered his room at last, hung his coat and hat on the door, and, crossing to his seat in front of a small mirror, sat down. “After all,” he said to himself, “I’m glad Talbotson won’t be here to-night. I’m not in a mood for talking, and the fellow bores me to distraction.” He lit a cigarette, leaned back in a more comfortable attitude, and for some minutes allowed himself to revel in the luxury of a perfectly blank state of mind. Suddenly the handle of the door turned—a solitary, isolated sound—and he sat up sharply in his chair. “Who’s there?” he shouted. There was no response. “I couldn’t have latched it properly,” he reasoned, and once again he leaned back in his chair and smoked. Five or six minutes passed in this fashion, and he was thinking of beginning to dress, when there was another noise. Something behind him fell on the floor with a loud flop.

Once again he turned swiftly round. It was his hat—a hard felt bowler. It had fallen from the door peg on which he had hung it, and was still feebly oscillating.
