Kate Martinelli has seen her share of peculiar things, but never anything quite like this; an ornate Victorian sitting room straight out of a Sherlock Holmes story -- complete with violin, tobacco-filled Persian slipper, and gun shots in the wallpaper that spell out the initials of the late queen. Philip Gilbert was a true Holmes fanatic, from his antiquated decor to his vintage wardrobe. He had a collection of priceless memorabilia that some would kill for as well -- and perhaps someone did. Eerily, the collection contained a manuscript, purportedly written by Holmes himself, that echoes the details of Gilbert's own murder. With the help of her partner, Al Hawkin, Kate must follow the convoluted mind of a killer -- a killer who may have trained at the feet of the greatest mind of all times.
