Michael Innes was a Scottish author who also wrote under the name of J.I.M. Stewart, which was his real name but as Going It Alone is a mystery it’s a Michael Innes book. It’s ages since I read any of the Stewart books and I hope to rectify that soon but from memory this book seemed more like those ones than his usual Innes books.
Maybe it was just because the storyline involves a family and there is no detective involved, just an uncle who helps his nephew when he gets mixed up with unsavoury characters which results in attempted murder, blackmail, kidnapping and robbery.
The uncle, Gilbert Averell, isn’t exactly completely innocent himself as he’s living in France as a tax exile from England and has entered Britain using a friend’s passport to avoid having to stump up more cash to the treasury.
It was first published in 1980 and is an enjoyable bit of light reading. Michael Innes had an incredibly long career as an author, over 50 years, and he usually manages to squeeze a bit of humour into his books too.
