London, 1889: Famous writer Oscar Wilde is the toast of London town. But when the body of a young man of his acquaintance is found in a dark attic room, surrounded by candles, he knows he can't rest until the killer is behind bars.

Appealing to fellow author Arthur Conan Doyle, creator of the great Sherlock Holmes, the pair set out to solve the crime.

But unravelling a real-life plot is very different to writing one. Can Wilde and Doyle outsmart the murderer hiding in the shadows, before it's too late?
