In Her Blood

Everyone is hooked on something.

It's not that easy to kick the money habit. After the world meltdown forces London's bankers to go cold turkey, people look elsewhere for a quick quid: the old fashioned East End.

So when investigator Catherine Berlin gets an anonymous tip-off about a local loan shark, the case seems straightforward – until her informant is found floating in the Limehouse Basin.

In another part of town, a notorious doctor is murdered in his surgery, and his entire stock of pharmaceutical heroin stolen. An unorthodox copper is assigned to the case, and Berlin finds herself a reluctant collaborator in a murder investigation.

Now Berlin has seven days to find out who killed her informant, why the police are hounding her and, most urgently of all, where to find a new – and legal – supply of the drug she can't survive without.
