So much for the letter.

Laying it aside, with a shrug of her expressive shoulders, Violet took up the manuscript.

Let us take it up too. It runs thus:

On the 17th of July, 19—, a tragedy of no little interest occurred in one of the residences of the Colonnade in Lafayette Place.

Mr. Hasbrouck, a well known and highly respected citizen, was attacked in his room by an unknown assailant, and shot dead before assistance could reach him. His murderer escaped, and the problem offered to the police was how to identify this person who, by some happy chance or by the exercise of the most remarkable forethought, had left no traces behind him, or any clue by which he could be followed.

The details of the investigation which ended so unsatisfactorily are here given by the man sent from headquarters at the first alarm.

When, some time after midnight on the date above mentioned, I reached Lafayette Place, I found the block lighted from end to end. Groups of excited men and women peered from the open doorways, and mingled their shadows with those of the huge pillars which adorn the front of this picturesque block of dwellings.

The house in which the crime had been committed was near the centre of the row, and, long before I reached it, I had learned from more than one source that the alarm was first given to the street by a woman’s shriek, and secondly by the shouts of an old man-servant who had appeared, in a half-dressed condition, at the window of Mr. Hasbrouck’s room, crying “Murder! murder!”

But when I had crossed the threshold, I was astonished at the paucity of facts to be gleaned from the inmates themselves. The old servant, who was the first to talk, had only this account of the crime to give:

The family, which consisted of Mr. Hasbrouck, his wife, and three servants, had retired for the night at the usual hour and under the usual auspices. At eleven o’clock the lights were all extinguished, and the whole household asleep, with the possible exception of Mr. Hasbrouck himself, who, being a man of large business responsibilities, was frequently troubled with insomnia.
