The Blood Road (Logan McRae, Book 11) by Stuart MacBride

The tenth Logan McRae novel from the No.1 Sunday Times bestselling author.
Scottish crime fiction at its very best. Some things just won't stay buried.
When Detective Inspector Bell turns up dead in a crashed car, it's a shock to everyone. Because Bell died two years ago. Or at least they thought he did.
Now Inspector Logan McRae has to work out where DI Bell's been all this time - and what was so important that he felt the need to come back from the dead.
But the deeper Logan digs, the more bones he uncovers. And there are people out there who'll kill to keep those skeletons buried.
