Sherlock Holmes and the King's Evil: And Other New Tales Featuring the World's Greatest Detective Read Free

situation. A good deal too much fuss is made about dust—which settles again almost as soon as it is brushed off.”
    The housekeeper had walked silently from the room, though we could feel that her eyes were still upon us from some vantage point just beyond the door. Holmes turned to the piano. He had come equipped with a black Gladstone bag that might more properly have belonged to a doctor. From this he took an instrument case, laid it on the table and opened it. He chose two camel-hair brushes, such as a painter might have used for fine work. To these he added two small bottles. The first contained dark powder, which was graphite of much the kind used for lubricating locks. The second was his own preparation, two parts of finely powdered chalk and one part of metallic mercury. These little bottles were accompanied by two insufflators to allow each powder to be blown gently on to any surface. In his waistcoat pocket, as usual, a folded magnifying-lens was readily available.
    For the next twenty minutes, Sherlock Holmes worked patiently and intently, his features drawn in a slight frown of concentration. He began with the light coloured powder of chalk and mercury, puffing it gently but accurately on to the black keys of the piano. Then he removed a little surplus with a camel-hair brush. When this was done, he took the graphite and the second insufflator, applying the darker powder to the white ivory of the piano keys. It settled like a thin drift of snow—and like snow it revealed the contours over which it lay, in this case those slight ridges imprinted by the exudations of the human skin.
    He took a little mirror from his pocket and angled it to catch the light from the windows. Then there began his long examination of each piano key in turn. I knew better than to interrupt him. It was half an hour before his back straightened and he stood up, the sharp profile animated and eyes glittering. He put down the little mirror into which he had been staring, seeking the best angle. The powders had now left on the polished ivory of the keys what I can only describe as a slight and brittle encrustation which a sweep of the hand would remove.
    “Of one thing we may be sure, Watson. The last person to touch this keyboard played upon it the ‘Préambule’ from the set of pieces entitled Carnaval, by the late and sublime Robert Schumann. It has not been dusted nor touched since then.”
     
    He seemed a little too pleased with himself for my liking.
    “How can you possibly say that?”
    “Very easily, my dear fellow. To begin with, we are only concerned with the last person to touch the instrument. I can assure you that all these prints belong to the same pair of hands. Only one person has played upon it since it was last dusted.”
    “Lord Arthur?”
    He raised a finger.
    “Look at the two topmost octaves of the keyboard in the right hand. No prints appear on the four highest keys. That is to say, G, A, and the raised notes of F and G. They are very often not required. We can safely forget them. But five other notes are also free of prints. Those are significant.”
    “Of what?”
    He sighed tolerantly.
    “Significant in your case, my dear Watson, of hours wasted in concert halls, fighting back sleep when the air was shimmering with the genius of Rubinstein or Paderewski. Before our little outings to the Wigmore Hall, I like to read the scores of the pieces to be played. Consequently I may tell you that in the right-hand of Robert Schumann’s ‘Préambule’ there are only five other keys—black or white—which are not touched. All are in the same two topmost octaves. They include the upper D flat and, in both octaves, the keys of E natural and B natural. Now you may study the keyboard of this splendid instrument and tell me for yourself which of those five keys have produced no finger-prints.”
    He was right, of course. I tried to salvage as much dignity as I was able.
    “Hardly conclusive proof of anything but
