The man’s name was Grindlay. He was a detective who owed his position of inspector in the Criminal Investigation Department mainly to my father’s recommendation. About six years previous a great fraud, involving a loss of something like thirty thousand pounds, was perpetrated upon my father’s bank by means of forged notes, and Grindlay, at that time a plain-clothes constable of the City Police, stationed at Old Jewry, succeeded, after his superiors had failed, in tracing the manufacturer of the notes to Hamburg and causing his arrest, extradition, and conviction. The ingenuity of the forger was only equalled by the cunning displayed by the detective, and in consequence of a question my father addressed to the Home Secretary in the House, Grindlay was transferred to Scotland Yard and soon promoted to an inspectorship. Therefore it was scarcely surprising that he should always show goodwill toward my family, and on each occasion we met, he always appeared unusually gentlemanly for one of his calling, and full of genuine bonhomie.
Immediately after the strange adventures of that memorable night on which I had been married to a lifeless bride, I had sought his counsel, but had been informed that he was absent in South America. It was now with satisfaction that I again met him, although I hesitated to speak to him upon the subject. Truth to tell I felt I had been ingeniously tricked, and that now after the lapse of months, even this astute officer could not assist me. No, as I stood beside him while he told me briefly how he had had “a smart run through the States, then down to Rio and home” after a fugitive, I resolved that my secret should still remain my own.
“Yes,” I said at length. “I heard you were away.”
“Ah! they told me at the Yard that you had called. Did you want to see me particularly?” he asked, fixing his dark-brown eyes on mine. He was a handsome fellow of middle age, with clear-cut features, a carefully twisted moustache and upon his cheeks that glow of health that seems peculiar to investigators of crime. In his well-made evening clothes and crush hat, he would have passed well for an army officer.
“No,” I answered lightly: “I happened to be near you one day and thought I would give you a call. What are you doing to-night?”
“Keeping observation upon a man who is going to the Empire,” he answered, glancing hurriedly at his watch. “Come with me?”
For several reasons I accepted his invitation. First because I wanted some distraction, and secondly because it had occurred to me that I might ascertain from him something fresh regarding the murder of Gilbert Sternroyd.
We lit fresh cigars, and, strolling to the Empire Theatre, entered the lounge at that hour not yet crowded. As we walked up and down, his sharp, eager eyes darting everywhere in search of the man whose movements he was watching, I inquired the nature of the case upon which he was engaged.
“Robbery and attempted murder,” he answered under his breath so that passers-by should not hear. “You remember the robbery of diamonds in Hatton Garden a year ago, when a diamond merchant was gagged and nearly killed, while the thief got clear away with every stone in the safe. Well, it’s that case. I traced the stones back to Amsterdam, but failed to find the thief until three weeks ago.”
“And he’ll be here to-night?”
