Fatal Development — Inga Simpson

When a body turns up in the courtyard of Dirk and Stacey's apartment, they turn to their friend and neighbor, Kersten Heller, for support. The police assume the death was accidental, but when it comes to light that the victim, a resident of the apartment building, was about to take legal action against the building's developers, Kersten decides there must be a connection. Kersten draws on old skills to investigate, hiding her activities, as well as details of her past, from her partner, Toni. She soon discovers what she's suspected all along. The victim was not alone on the roof when he fell, and evidence he'd collected for his case against the developer has gone missing. Threats and mysterious stalking put pressure on Kersten, and Toni grows impatient with her secrecy. With Dirk's help, Kersten sets a trap to prove her theories, but this case might unearth far more than she bargains for.
