Richard Osman Books

Was given the whole series of Murder Books, enjoyed the first one, gave up on second didn't read 3 or 4, except first few ages as it was more of the same then,m We Solve Murders, so many characters, all apart from odd one
thoroughly awful and insane. I did not find it amusing or a good murder mystery.
He must have many fans or they wouldn't sell, I can't see why though.
