‘Easily in the running for the best novella of the year’ – The Fantasy Hive

Infamous police detective Julia Torgrimsen is summoned to investigate the murder of Bruno Donaldson, a billionaire she worked with while undercover. But she doesn’t expect to find two bodies. Both are Bruno, identical down to the fingerprints – and both have been shot.

She finds herself on the hunt for a mysterious assassin who has been taking out London’s rich elite. But when she finally catches up with her quarry, she enters a world of deadly secrets: impossible documents about future stock market crashes; mysterious doppelgangers; and a conspiracy that threatens the entire human race.

To solve this mystery, Julia will have to revisit her undercover past and the brutal act that destroyed her once-legendary career . . .
