4. Book Review: The Dentist by Tim Sullivan
The Dentist is a standout in the British crime fiction genre. The plot is smartly structured with well-placed twists, but its greatest strength lies in its protagonist—DS George Cross. Rather than a tortured, brooding cop, we meet someone obsessive about truth, highly principled, and navigating the world through his unique lens.
Tim Sullivan’s writing is deliberate and empathetic. He does not exploit Cross’s condition for drama, but instead presents an honest and respectful portrayal. Though the pacing can feel slow in parts, it’s a trade-off for deeper character development.
