Murder is afoot among the footmen of Britain's Royal Household: a servant girl, Amy Macpherson, has been brutally slaughtered. And so our hero, Sholto Lestrade of Scotland Yard, is once again on the trail of mystery. As he tries to untangle a villainous web of conspiracy, the superintendent must venture north to Scotland.
His investigations take him from Balmoral Castle to the Isle of Skye to the North British Hotel, where he narrowly escapes an inferno in Room 13. The intrepid investigator contends with the most baffling clues he has yet encountered. But even when Lestrade is threatened by a fiendishly gruesome killer, he perseveres to get his man.
