Started the 4th of the series, and have been enjoying them. His characters are interesting, mysteries a bit gorry but not too bad and there's a bit of ghostly presence but it is not too much.
Grumpy Bob is a great name for a character. James Oswald is an interesting person, has a 350 acre livestock farm in North East Fife, where he raises pedigree Highland Cattle and New Zealand Romney Sheep. James Oswald web site
