Her Sister's Killer: A brand-new Northumbria CID Stone and Oliver thriller by Mari Hannah

4.0

“Her Sister’s Killer” is book five in Mari Hannah’s popular ‘Stone and Oliver’ series, featuring newly promoted DI Frankie Oliver and DCI David Stone. Based predominantly in North East England, this series is set in my local area, with places mentioned that are easily within touching distance. This always guarantees maximum enjoyment for me, ensuring my total engagement. 
 
Having read all of this author’s other series which features DCI Kate Daniels, I know that her police procedurals are top notch thrillers, that keep you on your toes until the exciting conclusion, and this book was no different. Although book five, it can be read easily as a standalone, though as ever when part of a series, following the character development is always best when starting from the beginning. 
 
I particularly enjoyed the impressively written surveillance scene, which actually felt like it was being played out in real time. It was tense, exciting and Frankie’s determination to get justice for an innocent victim was commendable. As a second plot line, the investigation into a cold case headed by Stone had to be kept secret from Frankie, causing issues within their personal and working relationship.  The dramatic reveal at the end was both astonishing and heartbreaking and well played by the characters involved. 
 
Overall I very much enjoyed this book, Mari Hannah switches between storylines seamlessly and at breakneck speed, ensuring a fast paced, tense read, that truly keeps you engrossed.
