Murder in Just Cause — Anne Cleeland

Doyle was back at Scotland Yard after taking maternity leave, and the powers-that-be had decided they'd ease her way by assigning her to assist DS Isabella Munoz, which was a fate only slightly worse than death.
Annoying, it was, that she had to answer to Munoz; not to mention that Munoz wasn't given many high-quality homicide assignments in the first place.
As a case in point, the first assignment out of the box was a possible suicide at the housing projects, something that happened with such regularity that it was a wonder the responding officer had even thought it worthy of a detective's notice. . . .
