I have been following Detective Erika Foster series and this one is the 6th book in the series. The story is set during Christmas, it is about Marissa Lewis who is young and beautiful and who is murdered in front of her house. As Erika tries to put the puzzle together through the bits and pieces of information shared by people who knew Marissa, it becomes complicated as a stalker who attacks both men and women – witnesses describe him as very tall, and wearing black clothes – but what makes him stand out from the usual attacker is the fact that he always wears a gas mask. Is he related to this murder case? The suspense runs almost close to the end. It keeps readers guessing! To make matters worse, Erika’s father-in-law has a fall and is hospitalized. So, Erika has to handover the case to Moss and rush to her father-in-law’s care. Will Moss be able to solve this case? You need to read this fast paced thriller to know more about the story. Robert Bryndza has emerged as one of the best crime writers and in turn, making Detective Inspector Erika Foster a memorable character. It is 4 stars from me.
