Murder Between the Pages by Josh Lanyon wasn’t the easiest book / murder-mystery to read and follow because the characters weren’t easily distinguished and different characters told the story in different chapters.
In the years just after WW2, an author of a soon-to-released novel is shot dead in a small bookstore during a book presentation. Two rival authors, Len and Felix, as well as the police set out to solve the case. The murder-victim had made enemies because of his not-so-fictitious characters in previous books so several in the audience had sufficient motive and opportunity.
The plot is well-constructed and the case is relatively straightforward for the ‘detectives’ (and the reader) to solve. The plot ticks along at a good pace and so the book is a relatively easy and comfortable read.
