The Sister Pelagia mystery series may not be as effortless a read to take in as Erast Fandorin, but it's well worth the effort. While the White Bulldog may be have a plot that is slightly less dynamic than the one Fandorin fans are used to, it is a refreshing change of pace. The language is beautiful, the characters are engaging and the sleuth and her posse (bishop Mitrofani and Berdichervsky) are at least as charismatic as Fandorin and Masa.
The series (there are only three novels in it) picks up the pace in The Black Monk and positively goes berserk in the Red Rooster, but the provincial charm of the White Bulldog is very enjoyable too.
Most Russian fans of Akunin consider the Pelagia trilogy to be a more workmanlike and even series than Fandorin, which has its peaks and valleys.
