Dark Corners

I enjoyed reading Dark Corners by Ruth Rendell which is set in London where a recently published author, Carl, rents out part of his house to Dermot.  Carl tries to write his second book while living off his savings and the rent from Dermot.  Carl inherited the house and everything in it from his father who collected medicines.  An "unfortunate incident" occurs when Carl sells one of the medicines and this is compounded when Carl learns the transaction was witnessed by Dermot.  Carl's life begins to unravel as he tries to see a way out of the mess.  There are other threads to the story which have little to do with the main story.  I've read and enjoyed most of Rendell's work.  Sadly this is her last book and it is certainly not her best. 3/5
