An Agent for Penelope (Book 31) by Christine Sterling
A refined bookworm determined never to marry; a pugilist and seasoned agent determined to work alone; the case that will test their tenacity.

Penelope Chapman's youngest sister leaves town with a traveling preacher and Penny is sure something is wrong. She goes to the only person she's sure can help her get to the bottom of it–her twin sister, Marianne. She hopes Marianne will convince the Pinkerton Detective Agency to get involved. What she didn't count on was the gruff bare-knuckled fighter that appeared to have more bruises than sense, who is assigned to the case.

Angus Hightower was avoiding the Pinkerton Denver office at all costs since the policy on marrying male agents to the new female agents. He becomes a bare-knuckle fighter for a case until a scandal involving one of their own sends him back to Denver. One look at Penelope Chapman and he dives into the temporary marriage with the intention of solving his case, finding the girl, and impressing his new wife.

Will Penny and Gus find the youngest Chapman girl before it is too late? What happens when they discover that Angus' case and the disappearance of Penny's sister might be tied together, and the danger is more than either of them realized? When Penny goes missing, will Angus be able to save her, or will his love and fists not be enough?

An Agent for Esme (Book 32) by Amelia C. Adams
Matthew Harrison, Pinkerton agent, has always prided himself on being ready and willing to accept any case he's assigned. He's a team player, after all. But when his new partner, a pretty young female agent from the Chicago office, shows up to escort him to their assignment in Santa Fe, he's not at all sure what to make of her. He's never met anyone so focused on being prim, proper, and precise, and he believes she just might be the most irritating woman he's ever met.

Esmerelda Carter has one objective, and one objective only - to reach Santa Fe, find the missing agent they've been sent to find, and turn in her report. She doesn't have time for fun and games, and she certainly doesn't have time to entertain thoughts about her handsome new partner. Yes, the case does require that they get married, but that's temporary, and soon they'll be parting ways again.

But the case isn't what it seems, and soon they're depending on each other for their very lives . . . which does have a way of bringing people closer together.

An Agent for Alexina (Book 33) by Laura Beers
Alexina Kimball is an experienced Pinkerton Agent, and arguably one of the best agents at the Chicago office. She works alone and always catches the bad guys. However, everything changes when she's transferred to the Denver office and is assigned a partner.

Finally, Dawson Wayne's dream of becoming a Pinkerton Agent is becoming a reality. The only catch is that he must marry his trainer… a beautiful, infuriating woman.

Together, they're sent to the small town of Hidden Ditch, Kansas. Their case: discover the whereabouts of two schoolteachers who've gone missing. As the stakes increase, can Alexina and Dawson work together to solve the case, or are they both too stubborn to recognize that there is more on the line than just the missing schoolteachers?

Can two headstrong agents learn to trust each other's instincts when love is on the line?
