Cardinal Black by Robert R. McCammon

5.0

Cardinal Black, the seventh novel in Matthew Corbett's series, picks up the plot from Freedom of the Mask. First, Matthew has to strike a deal with Professor Fell to save his love and friend. Then, with a charming assassin, Julian Devane, he needs to recover the book of botanical wonders (potions, poisons, drugs) from Cardinal Black.
It's one of the fastest and most brutal books in the series. However, it also suggests Satanic forces may be at play, a thing to explore in the next book.
The series is brilliant, and McCammon's characterization skills are uncanny. Without spoiling too much, Matthew realizes sometimes you need a bad man (or to become one) to get the job done.
I can't wait for the next book in the series. I've binged seven books, 3 545 pages in a month. It's one of the finest series I've ever read.
