Mick Herron‘s thriller (the first in the OXFORD SERIES) mixes sharp one-liners, genuine twists and cynicism but Sarah‘s convoluted back story didn‘t work for me given what you see of her before it‘s revealed. Zoë Boehm makes a bigger impact despite limited page time and I found both her and the dangerous and driven Michael Downey more interesting characters. It‘s an entertaining read and I will read on, but it‘s not as good as SLOUGH HOUSE.
