British investigator David Cleveland hadn’t come to Oslo dressed for the Norwegian weather. But he didn’t know what cold really was until someone tried to drown him in a fjord.

Of course, it could have been an accident that the speedboat cut David’s dinghy to ribbons. Just as it could have been a coincidence that champion jockey Robert Sherman had disappeared from Norway right before his wife was due to give birth and before the National, a race he was certain to win.

But accident and coincidence couldn’t explain the gruesome string of deaths that David Cleveland would find was meant to include his own.
