Kensington Court is a refuge for various reasons: escaping an abusive partner, or hiding from debt, or descending into genteel poverty due to dodgy investment advice. All the characters here have a history that colours the present. Some are likeable, others the opposite; but when some of them are found dead in locked apartments, everyone is under suspicion. Red herrings galore include the strange doorman, the fraudulent advisor, and the offensively domineering lady and her many victims.
Enjoyable suspense, though I guessed how it was done quite early on.
