 When one of the women employed at Scrubbers is killed at work, the team sets up shop to find out why. Not that well liked by her co-workers, it seems unlikely that workplace rivalries would lead to the suffocation death of the victim. But she was also tidying up the homes of a number of prominent members of a golf club, and maybe making a cleaning off of their secrets as well. Meanwhile Alex toys with the idea (and her teammates) of accepting an offer to move to London and promotion to DI, just as Gil finally gets word from his absent wife.
