Note: Published as a chapbook titled "Hercule and the Doctor" or "Poirot and the Doctor" in 2011.

Synopsis: Twenty years ago, Harold's little sister vanished into the decrepit mansion known as the Bonehouse. Now, Harold is a middle-aged Agatha Christie aficionado, still obsessing over what might have been if he'd only been a little braver that day, if he'd only been a little bit more like his childhood hero—the fourth Doctor. But when Harold meets an out-of-town cosplayer in full Tom Baker kit, he decides to do as the Doctor would have done, and return to the Bonehouse in search of answers. But can one amateur thespian and one drunken science fiction fan really solve this mystery, and put little Elizabeth to rest?
