Strike investigating, first a disapparence, then a murder.
The side story is actually a background story about his past ans how he lost his leg, and how he saved someone life.
His disability is limiting him in way that is frustrating. He has to drive automatic as his knee is injured and he is in pain.
Robin offered to drive him and he finally taken up her offer. The driving itself is a turning point for Strike to put even more trust into her. She had advanced driving skill.
Cool. Enjoying this.
