Durham Deception — Philip Gooden

For the newly-weds Tom and Helen Ansell life is no honeymoon, as they are drawn into a murky underworld of Victorian spiritualism and stage magic when they're sent on a mission to the stunning cathedral city of Durham. Not only must they investigate Helen's Aunt Julia, who has mysteriously fallen for a medium, but also solve the riddle of the sinister Lucknow dagger. Until suddenly things go from bad to worse when a body turns up and Helen herself is accused of murder.
