Should you find yourself in need of a discreet investigation into any sort of mystery, call on Jesperson and Lane . . . ''Arthur Conan Doyle would have approved,'' says George R.R. MartinMiss Lane is puzzled by Jasper Jesperson''s interest in what seems a very minor theft -possibly even a prank - from the storerooms at the British Museum. But London in the 1890s is rife with secret organisations, cults and individuals eager to acquire some of the legendary magic of ancient Egypt. The deeper the two detectives dig, the more hidden crimes they uncover, and the higher the death toll mounts. And at the centre of it all is the ''Mystery Mummy'' recently acquired by the museum. ''Tuttle does a lovely job of putting us back in the foggy streets of Victorian London'' George R.R. Martin, author of The Game of ThronesAre the deaths and madness truly caused by a mummy''s curse? Or is there a scheming, living villain to be apprehended? ''A most engaging detective duo'' Mark Douglas Home, author of The Sea Detective and The Woman Who Walked Into The SeaJesperson and Lane, with their experience of past investigations involving psychic phenomena and supernatural events as well as ordinary human criminality, are surely best placed to find the truth.Jesperson and Lane, at your service.
