Santa's Sticky Fingers. Helen Shepherd Mysteries, #13

Normally, Detective Inspector Helen Shepherd doesn't deal with petty crime and pickpockets. But when the Christmas market in Kingston upon Thames is hit by a wave of thefts, Helen and her team are called in to help out. Harry, a homeless man who always hangs around the market, seems to be the most obvious suspect. But there is also the mysterious man in the black leather jacket some witnesses claim to have seen.
Or maybe, the thief can be found much closer to home. Can Helen and her team crack the case in time for Christmas? This is a holiday novelette of 7800 words or approx. 26 print pages in the Helen Shepherd Mysteries series, but may be read as a standalone.
