Following the events of the last book, Hell To Pay Kay is only returning back to work and is therefore on light duties – much to Kay’s annoyance! DI Devon Sharp is still suspended so Kay decides that she’ll clear both her and Sharp’s names. So up to this point I have said that the books can be read as standalones but better to know the background however with Call To Arms it is my opinion that you need to have read Hell To Pay as the books are intrinsically linked. Trust me, this is no hardship as the series is fabulous and so quick to read as you do not want to put them down once started!

Kay starts relooking at a cold case which may help Sharp’s case if she can prove that it wasn’t fully investigated – a motorcyclist died following, what appears to be a accident whereby he skidded and lost control of his motorcycle. At the time, Sharp was working for the military police however as this happened away from barracks, he was not directly involved in the investigation into this young army private's death. However the more digging that Kay and the team do, the more complicated the investigation becomes, and not just because it involves a senior colleague….that is all I am saying about the plot!!

As with previous books in the series, this is brilliantly written – we see a different side of Kay and the team as the cold case is ten years old. Forensic techniques have moved on a lot since then, also they face issues of finding old witnesses who have either moved on, died or simply forgotten the details of the events at that time.

Another brilliant read in this gripping series.
