Blood At the Bookies by Simon Brett

All bets are on when there's a body found at the bookies...When Jude wanders into Fethering's local bookies she has no idea that she will shortly be investigating the murder of Polish immigrant Tadeusz Jankowski. With her partner in crime, friend and next-door-neighbour Carole, she's determined to discover who killed him - and why? There are several favourites in the running: A mysterious woman in the bookies? The charming lecturer at the university? Or the mysterious attacker who Jude only narrowly escapes from? Talking to suspects and gathering information, the amateur investigators try to piece together the broken trail of the young immigrant's life. But in this race there's only one winner - and it could be that they are pipped at the post by a cold and calculated killer...
