Sarah's Gift. The Island Connection, #17

Inspector Penny Chakyar is on holiday in India when, back on the Isle of Man, Hjalmar, her long-time partner, is murdered. Detective Inspector Sarah Flemons, is tasked with finding the person or people responsible and bringing them to justice. But, on her return, Penny has other ideas and calls in a hired killer. She doesn't want to see her partner's killers in court - she wants to see them dead. Since Penny is also a police inspector, Sarah realises that such a contract would place Penny on the wrong side of the law and, long-term, probably destroy her self-esteem and her career.
The contract killer enlists Sarah's help to resolve the issue. Unfortunately, of course, that also makes Sarah complicit - so, will she be able to live with the consequences, or is there a way out? Is there a way that both Sarah and Penny can keep their hands clean?The bodies keep mounting up as Hjalmar's killers are unveiled. But it's not only th contract killer who's responsible. Demonic forces are at large and, finally, it becomes a fight of good over evil.
But who will be crowned the winner?
