The Last Dance by Mark Billingham

Meet Detective Miller: unique, unconventional, and criminally underestimated. He's a detective, a dancer, he has no respect for authority ­- and he's the best hope Blackpool has for keeping criminals off the streets. Meet Detective Declan Miller.

A double murder in a seaside hotel sees a grieving Miller return to work to solve what appears to be a case of mistaken identity. Just why were two completely unconnected men taken out?

Despite a somewhat dubious relationship with both reality and his new partner, can the eccentric, offbeat Miller find answers where his colleagues have found only an impossible puzzle?
