Black Diamond Detective Agency reviewed on NewsARama
"Eddie Campbell has officially established himself as the master of turn-of-the-20th-century comics....
Mixing a mystery that keeps you guessing until the very end with great action sequences and compelling characters, The Black Diamond Detective Agency may have been intended for the screen, but it’s hard to imagine how the story will ever surpass the treatment it receives here. You can smell the air of Chicago in 1899, and John Hardin is one of the most engaging protagonists to grace the printed page in recent memory. Definitely recommended."
