Don't buy this book expecting a work of art. Nor even a book that's been well-edited and typeset. Don't go into it expecting a complex mystery with a dazzling solution arrived at by brilliant deductive reasoning, come to that. If you expect any of the above, you'll be a bit disappointed. Quite a bit.
If, however, you want a moderately entertaining time-passer, with occasional flashes of genuine wit, then put your money down.
Our hero, Detective Inspector Walter Glass (glass of water- geddit?) gets involved in a horse race fixing scam. At the same time, his colleague (and son-in-law) investigates a massive cocaine importation business. Could these two cases be connected? What was the title of the book again?
There's not much to add, as things plod towards their inevitable conclusion, and there's something reminiscent of Joyce Porter's Dover about things(although Glass isn't actually hopeless, he's just old-fashioned). I think the services of an editor and a proof-reader might have helped.
