Philip Gilbert was a true Holmes fanatic, from his antiquated decor to his vintage wardrobe. And no mere fan of fiction's great detective, but a leading expert with a collection of priceless memorabilia-a collection some would kill for. And perhaps someone did: In his collection is a century-old manuscript purportedly written by Holmes himself-a manuscript that eerily echoes details of Gilbert's own murder. Now, with the help of her partner, Al Hawkin, Kate must follow the convoluted trail of a killer-one who may have trained at the feet of the greatest mind of all times.
