Red Leech (Young Sherlock Holmes 2)

Sherlock knows that Amyus Crow, his mysterious American tutor, has some dark secrets. But he didn't expect to find a notorious killer, hanged by the US government, apparently alive and well in Surrey - and Crow somehow mixed up in it. When no one will tell you the truth, sometimes you have to risk all to discover it for yourself. And so begins an adventure that will take Sherlock across the ocean to America, to the centre of a deadly web - where life and death are cheap, and truth has a price no sane person would pay . . .
