In early 1925, the Honourable Daisy Dalrymple Fletcher, recent mother of twins, resumes her journalistic career by agreeing to write a piece about the Tower of London - the Bloody Tower - for an American magazine. Invited to observe the centuries old ritual Ceremony of the Keys, she's spending the night (her first time away from her babies) since the complex is locked and guarded, and the high walls are surrounded by a disused moat. Having been given a tour of the Crown Jewels, interviewed and observed the Yeoman Warders, and met the Ravenmaster, Daisy has more than enough material for her article and decides to leave as early as possible the next morning to return to her family. But when walking down the stairs, she almost trips over the dead body of one of the Yeoman Warders. That there's something seriously amiss cannot be denied, due to the pike sticking out of his back. With her husband, Scotland Yard DCI Alec Fletcher assigned to resolve the case, Daisy once again finds herself in the middle of a case of murder most foul.
In Dunn's cunning 16th Daisy Dalrymple mystery (after 2007's Gunpowder Plot), the charming Daisy stumbles over the corpse of the Chief Yeoman Warder at the Tower of London. Daisy and her husband, Scotland Yard's DCI Alec Fletcher, team up to unmask the killer. Daisy does all the really clever sleuthing, but she kindly allows her hubby to think he's putting things together himself. Things get tricky when one of the chief suspects, who may also be a blackmailer, disappears. And then there's the curious matter of the manner of death: the autopsy concludes that the Yeoman Warder died of a broken neck, so why was there also a partizan, or Yeoman Warder's halberd, sticking out of his back? Appropriate historical detail and witty dialogue are the finishing touches on this engaging 1920s period piece.
