Pinkerton Matchmaker (Christine Sterling) Books in Order

Pinkerton Matchmaker blends two strong romance engines, investigation and courtship. The books live in a western historical world where danger, secrecy, and law-enforcement work sit right beside matchmaking, mail-order plans, and unexpected attraction.

That combination gives the series its particular energy. A heroine may be caught up in a case, a man may be working under orders, and both of them may discover that the practical assignment in front of them is harder to manage than the feelings growing underneath it. Christine Sterling's books in the line, including The Pinkerton Matchmaker, An Agent for Claudette, An Agent for Penelope, An Agent for Marianne, and An Agent for Pearl, all lean into that mix of motion and heart.

These are not mystery novels first and romances second. The love story still leads. But the Pinkerton connection gives the books sharper stakes than a purely domestic courtship series would have.

Readers who want clean historical romance with a little more suspense, hidden identity, and professional danger will probably enjoy this setup. It is fast, plotty, and still very interested in whether two people can build trust before the case is over.
