One day Arthur Conan Doyle will create the greatest detective of all -- Sherlock Holmes. But right now Artie Conan Doyle is a twelve-year-old Scottish schoolboy with a mystery of his own to solve.

While sneaking out to explore Greyfriars Kirkyard by night, Artie and his best friend Ham spot a ghostly lady in gray and discover the footprints of a gigantic hound. Could the two mysteries be connected?

These strange clues lead them to a series of robberies carried out by the sinister Gravediggers' Club and soon they find themselves pitted against the villainous Colonel Braxton Dash.

Will Artie survive his encounters with graveyards and ghosts in the foggy streets of the nineteenth century -- or will his first case be his last?

Robert J. Harris, author of The World's Gone Loki series and Will Shakespeare and the Pirate's Fire, brings the young Conan Doyle to life in this ingenious detective story full of twists, turns and clever reveals.
