The Holy Trinity Duet by M.E. Clayton is a three-book fiction series that opens with The Bishop in 2021. The Cardinal followed the same year, and Enemy of the State arrived in 2025 as the third entry. The titles suggest a world of power and religious authority, with characters named after church hierarchy.
Readers should start with The Bishop and continue through The Cardinal before picking up Enemy of the State, since the storylines carry forward across all three books. M.E. Clayton has written several related series, and fans of this duet-plus-one may want to explore The Holy Trinity series for more from the same author.
