Presently a peal of girlish laughter rings out on the soft May air, and the girls wave their hands to each other in token of adieu.

The pretty girl in the pink blouse goes back again into the room, and as we move away there comes through the open window an air from the latest Gaiety success.

Both these houses belonged at one time to an elderly clergyman. One was empty—the one in which the Gaiety music is being played—and a workman was employed in doing it up that it might be re-let.

The old clergyman went out one morning to see how the repairs were going on, and that was the last that was seen of him for some time.

His elderly housekeeper at his residence in the other square expected him back to dinner. But instead of her master the workman came. That was the last that was seen of the old housekeeper for some time.

A few days later a van stood at the door. The caretaker, a workman, explained that he had been left in charge and had to send a box away. The vanman picked up the box to carry it out, and found his hand stained with blood.

He uttered a cry of alarm and exclaimed, "What does this mean?" Then the workman ran out of the house and the van-man ran after him. The fugitive, who had hurriedly swallowed a dose of laudanum, was arrested by a policeman. Other constables proceeded to the house and opened the box.

In it was the body of the housekeeper. She had been strangled with a rope, which was still round her neck. The rope had been drawn so tightly that it had forced blood from the victim's mouth. The murderer had not calculated on this, and owed the detection of his crime to the circumstance.

Search was made at the house in the other square, and the body of the clergyman was found buried in the drain.

That is the story of two houses in quiet Chelsea squares. In the one we have just seen a charming girl chatting with her friends, and we have heard her playing the piano merrily.
