In The Silkworm, Clement Attlee Court is the area where Kathryn Kent lives. It is composed of old council blocks, “ugly square brick towers with balconies on every floor…”
Kathryn lives in a council block called Stafford Cripps House, which was the block “nearest the road, set just behind a low, modern medical centre.”
Later in The Silkworm, both Strike and Robin go to Stafford Cripps House to talk to Kathryn Kent and Pippa Midgley.
