Victoriana fans who thought that Palmer’s first three adventures of amateur sleuth Charles Dickens and his friend and amanuensis Wilkie Collins (The Hoydens and Mr. Dickens, 1997, etc.) weren’t literary enough will be delighted when they team up with Rev. Charles Lutwidge Dodgson, a.k.a. Lewis Carroll. This time, the three set out to solve the murder of an Oxford historian who came a long way from Christ Church College to be found dead in the disreputable neighborhood of Limehouse Hole.
