Private investigators Timothy Badger and Benjamin Watson take on another unusual and baffling case in Victorian London when a mummy unwrapping party takes a chilling turn.

London, 1895. Although their last high-profile case was a huge success, private detectives Tim Badger and Benjamin Watson know they can't afford to turn down any work, despite financial assistance from their mentor, Sherlock Holmes.

So when the eminent Doctor Enoch Sawyer of St Bart's Hospital asks Badger if the duo will provide security for a mummy unwrapping party he is hosting, Badger doesn't hesitate to take the job. After all, how hard can guarding the doctor's bizarre Egyptian artifacts be? But with Doctor Sawyer running late for his own party, the 'genuine' ancient sarcophagus of Runihura Saa is unraveled to reveal the remains of . . . Doctor Sawyer! Suddenly, the pair are drawn into a case that's stranger and twistier than they could ever have imagined.
