Ooo, thanks for the reminder! I very much enjoyed those as well and should dig them out again.

Did you read any of his other books? Would you recommend them?

I was a bit disappointed with the fourth book set in the The First Law universe. Possibly it was Best Served Cold but I'm not sure. It felt more like a rehash and it was missing whatever made the first books special. And it put me off trying his other books ever since.
