Two people, one bleeding

And here's another review of Any Human Face, from The Fiction Desk this time. It's typically perceptive and I particularly enjoyed this sentence:

The character interactions are driven by Lambert’s interest in the way people react to power and vulnerability in themselves and in each other; it’s tempting to say that the archetypal Charles Lambert scene is one in which two people are in a room, and one of them is bleeding.

Fascinating, though I'm not sure how true this is. Any ideas?
