the man came to die, what attracted your attention, and why you walked over to him just at the moment of his death.â
Henry shuddered. âTo tell you the truth, Inspector,â he said, âI hardly know.â
âBut you must have some sort of idea, surely.â
âA vague idea, anyhow,â contributed Sergeant Cunningham, who had accompanied his chief on this errand of investigation, but who had hitherto remained silent.
Henry giggled. It is regrettable to admit the fact, but he was the type of man who would giggle on occasion.
âWell, gentlemen,â he said. âI am one of those strange peopleâthe students of humanity. The dead man attracted my attention because he was, if I may say so, of such a striking and unusual appearance. I found myself watching him almost unconsciously, in the way that one sometimes does watch a stranger who strikes one, if you understand me.â
âI understand you, Mr. Fairhurst,â said Shelley in sympathetic tones, âbut I still want answers to a few other questions, you know.â
âFire away, Inspector,â Henry answered, and then, conscious that this piece of slang was somewhat undignified for a man of his position in the social world of Streatham, he added: âOr, if I might borrow a word from the gangster films, I would say, âShoot!ââ
âFirst of all,â remarked Shelley briskly, âdid you see anyone else approach the man in the last few minutes before he died?â
Henry reflected. âI have a sort of vague notion that someone was walking away from the man as I approached,â he admitted. âItâs only the vaguest of impressions, though, and I couldnât possibly swear to it for a moment.â
âWas it a man or a woman?â asked Cunningham, with a glance of apology at his chief. âWill your memory give you any information on that point, Mr. Fairhurst?â
Again Henry reflected deeply for a moment before replying.
âItâs difficult,â he murmured. âYou see, I may be getting some quite innocent person into trouble if Iâ¦â
âDonât worry about that,â Shelley interrupted. âIf any innocent person is involved in this case we shall clear him without the slightest difficulty. Donât worry about that for a moment, Mr. Fairhurst.â
âWell,â Henry admitted somewhat unwillingly, âI must say that I have an idea that a woman had been talking to the man before he died. But I couldnât swear to it. You see, there are so many people in that Reading Room that it might easily be a mistake on my part. Some perfect stranger might trip over the manâs chair, and pause to apologise. That might easily account for the fact that I thought a woman was talking to the man. Or,â he concluded somewhat lamely, âthere may not have been any one there at all.â
âGot that, Cunningham?â asked Shelley. His assistant nodded.
âOnly one thing, sir,â he added.
âYes?â Shelley was always prepared to take a hint of a useful line of investigation.
âDo you think Mr. Fairhurst could be induced to remember the sort of clothes the lady was dressed in?â
Henry looked from one detective to the other with some surprise. What on earth would these men ask next? How did they expect him to remember the attire of a lady of whose very existence he was not certain?
Yet he found himself answering. âI have a definite impression of a youngish lady, rather pretty, and dressed in some sort of dark jumper and skirt,â he said. âFurther than that Iâm afraid I cannot go.â
âVery useful, Mr. Fairhurst,â was Shelleyâs comment. âVery useful indeed. I expect weâll lay our hands on that young lady before many hours are past; then maybe we shall be wiser than we are now on the subject of Arnellâs death.â
âArnell?â Henryâs tone was
