The Last Dance - Mark Billingham

The first new series in two decades from multi-award-winning international bestseller Mark Billingham that introduces Detective Miller: a man who's unique, unconventional, and criminally underestimated.
Maverick sleuth Declan Miller is back at work following the murder of his wife (and amateur ballroom dancing partner) Alex. Working with new partner and heavy metal enthusiast DS Sara Xiu, he is tasked with investigating the double killing of gangland family scion Adrian Cutler and IT consultant Barry Shepherd at the Sands Hotel. Initial evidence suggests a hired gun and a botched job. The search for the hitman begins and Miller begins to reconnect with his old network-his ballroom dancing friends, homeless informant Finn, and even the ghost of his wife who keeps showing up in his kitchen. The fact Alex had been investigating the Cutler family prior to her death complicates things, and as Miller gets closer to the truth, he realizes the danger is walking right up to his doorstep...
