Murder at Matterdale (Detective Simon Wayland #2)

Detective Simon Wayland is out training his Mountain Rescue dog on the fells when he stumbles across two bodies. Both are covered with horrific stab wounds.

More chillingly, each body has a coloured coat toggle shoved in its mouth.

Working with his new boss, the dynamic DCI Collette Matthews, Wayland faces a puzzling investigation that offers no clear leads.

Then two more victims are found. Each with different coloured toggles in their mouths.

Wayland is convinced a cold-blooded serial killer is playing a ruthless game. And there are no clear rules. Wayland and Matthews must crack the case before more bodies start to pile up.
