I've only voted for my own nomination this time,
In Pale Battalions, (
) because I really would like a Robbert Goddard to win. I genuinely think a lot of MR readers would enjoy his books (at least those that enjoy family murder mysteries, particularly ones that go back generations, as many of his do).
Goddard has a fairly large canon of work, and is the favourite living author of William Haig (ex-leader of the Conservative Party and our current Foreign Secretary).
