Chameleon - The Death of Sherlock Holmes

When Lady Halifax is brutally murdered at Forsythe Hall, the finger of blame points squarely at a guest who had fled the hall during the night - Charles Lidell.  But her ladyship's granddaughter, Ferris Buckley, is not convinced of Lidell's guilt, and turns to Sherlock Holmes for help.

The case has Holmes at his wit's end, for he is facing "The most profound criminal of my career."
