But there’s no time to mull on the new distance within their professional relationship, as a frightening visit from a potential client puts a new case on the table - and Robin and Strike set to work looking into reports of a strangled child.
With the detective agency thriving, the duo are also recruited to investigate the blackmail of a Government Minister and Robin is tasked with going undercover in the House of Commons.

Fearing their witness is in danger, they redouble their efforts to find him. As Robin deals with frustrations in her marriage and Strike accepts a dependency on a new girlfriend, their investigation deepens.

Strike pieces together a theory by interviewing many of the key players in the case - but ends up fending off an attack in the process.
While Robin’s marriage reaches crisis point, Strike’s new romance isn’t going so well either. Robin and Strike regroup, and the person blackmailing of the Government Minister becomes their prime suspect - but they now believe that there was an accomplice...

As the police arrest a suspect, things finally click into place for Strike - but with his partner unwittingly walking into danger, the solving of the case might have come too late for Robin…
