I’ve come further with this site than I thought I would. Just put up another page of unclassifiable books. Since I don’t stick to one genre all the time, it’s inevitable that there will be some outliers which refuse to fall neatly into one category.
However, some of these have been the most fun to write, and have attracted a fair amount of critical acclaim. Tales of Old Japanese gets almost universal praise, and I suppose it is the most “literary” of all my published writing. You might want to give it a go – although the protagonists of the stories are older Japanese people, you might find yourself identifying with them and their predicaments.
There’s also an attempt at a Father Brown pastiche. Much more difficult than a Sherlock Holmes pastiche for a variety of reasons.
