"About half-past six this morning a murder of a peculiarly atrocious character was discovered in that block of flats known as Embankment Mansions in Whitehall Court. It seems that Colonel Napier's valet, a man named Richardson, who was early awake in consequence of an attack of toothache, was startled by hearing what he believed was a shout for help proceeding from his master's room. He went at once to the door and knocked, and, on getting no reply, he turned the handle and entered, when he was horrified to see Colonel Napier stretched on the bed, with a great dagger-thrust in the region of his heart, and quite dead. An open window showed at once the means chosen by the murderer to effect an entrance, which was rendered all the more easy by the fact that an iron pipe ran past it on its way from the roof to the earth. The valet sprang at once to the window, but he could see no sign of any person, and darting to an inner room he turned on a district messenger-call for the police. Then he ran back to the bedroom. The colonel could not then have been dead many seconds. Everything pointed to that. Nor was it clear why the crime had been committed. Nothing had been removed from the bedroom--nothing at all. Detective-Inspector Naylor and other officers were quickly on the scene, but although they searched they could not find any trace of the murderer or of the weapon with which the terrible deed was accomplished. At the time of writing, indeed, the crime is enveloped in mystery, for Colonel Napier, who was formerly Member of Parliament for Hereford, and had won high recognition for services on the Indian frontier, was considered by all a most popular man. He was a widower, and leaves only one child, a daughter, who, luckily, at the time of the tragedy was away on a visit." For a few moments after reading this I confess I felt at a loss to speak, to move, even to think--the thing was so hideous, so appalling, so complete. The horror of it all seemed so acute that it crushed me beneath its weight. I could only sit with eyes that, look where they would, perceived nothing but the dread scene in the death chamber--that man I had a keen affection for stricken to the heart. Maybe some of us who suffer such awful shocks get curiously clairvoyant in the moments of our greatest trial. I cannot tell. I only know I descended from that cab, paid the man his fare, and entered my office in Stanton Street, like one in a trance. All the time my brain was beating through a cloud of horror, doubt, and suspicion; but, finally, as I flung myself into a chair in front of the fire, every point appeared to clear for me as though by magic. Then one terrible question stared up at me with awe-inspiring distinctness: Was this crime the work of Jose Casteno?
