The sixth and final book in the Mercy Fitzpatrick series, A Merciful Promise sees Mercy go undercover in a militia group when the ATF need some help in a hurry. Their agent is due to go in the following day and has come down with shingles, and Mercy is the only agent in the FBI or ATF who fits the bill physically. Her ‘be prepared’ philosophy makes it a no-brainer; she can think on her feet and fit in with the militia members almost seamlessly.
With Mercy completely out of contact, her fiancé Truman is at something of a loose end - at least, until the bodies start turning up. Three in all, naked males who were apparently executed at close range. When the murder cases tie back suddenly and shockingly to Mercy’s undercover operation, Truman might just be the only one who can help her.
I’ve really enjoyed this whole series, and this is an absolutely stellar final installment. Mercy is at her best when forced into survival situations and she got to really shine here. The bloated cast which got on my nerves a bit in the last couple of books is pared back here to focus primarily on Mercy and Truman, and it really works well.
