Arson, accident or murder?

After a fire rips through a North London tower block, two bodies are found locked in an eleventh-floor flat. But it is the third victim - the MP Geoff Armstrong - that requires the presence of detective Maeve Kerrigan and the murder squad.

As Maeve picks through the wreckage, she will uncover a secret world where everyone has something to hide . .
