I found Engleby disturbing but was also intrigued as to how a writer could show such beautiful sensitivity toward women in novels like Charlotte Gray, and then create a monster like Mike, who has no respect for anyone.
I admire Faulks' writing ability immensely. He has such wit and lovely turns of phrase. He is one of my favourite writers.
I've always been interested in criminal psychology and this could read as a warning I think. How easy it is for society to produce people like Mike.
