Carmine Delmonico is a police captain in Holloman, Connecticut — a fictional Yale-adjacent university town McCullough built specifically for this series — investigating cases that repeatedly implicate the town's wealthy, insular academic and scientific elite. On, Off opens with a serial killer targeting young women connected to Chubb University (McCullough's stand-in for Yale) and dismembering their bodies in a way that points toward someone with genuine medical or research expertise, setting the template for a series that treats institutional privilege and scientific ambition as breeding grounds for murder as often as any conventional motive.
Written after McCullough completed Masters of Rome and largely concurrent with several of her later standalones, the five Delmonico novels are a late-career return to contemporary crime writing from an author who'd otherwise become known for historical and multigenerational fiction. Too Many Murders escalates into a Cold War-era espionage plot with multiple murders across a single day, while Naked Cruelty, The Prodigal Son and Sins of the Flesh keep circling back to Holloman's tangled web of Chubb professors, socialites and old-money families, with Carmine's own extended family increasingly drawn into the investigations as the series progresses. It's a tighter, more plot-driven read than Masters of Rome, closer in spirit to a classic police procedural, though McCullough's interest in institutional power and old-money dysfunction carries over from her historical fiction.
Publication order, starting with On, Off (2006). Carmine's investigative team, his relationships and his extended family all develop across the five books, and Too Many Murders in particular sets up character and institutional threads that continue through the remaining three, so this is a series better read start to finish than sampled individually. It's a complete, five-book run published between 2006 and 2013, with no additional entries after McCullough's death in 2015.
