A Bullet for Father Christmas [EPUB ebook] 
A Helen Shepherd Mystery

When two men dressed up as Father Christmas rob a London jewellery store and one of them ends up dead on the floor, shot by his own accomplice, it’s certainly one of the more unusual cases for Detective Inspector Helen Shepherd and her team. But as Helen begins to investigate, it turns out that the case is even more bizarre than she suspected.
This is a holiday mystery novelette of 9300 words or approx. 30 print pages in the Helen Shepherd Mysteries series, but may be read as a standalone.
