My mum recommended me this book as I've been fascinated by lip reading recently. This was my first time reading a Colin Dexter book and even though my mum warned me how confusing they can get and how you'll need to get the dictionary out every now and then for a new word, I didn't really realise how often that would be. The plot became more and more complex and interwoven as the book progressed and as someone who struggles to keep track of copious amounts of information at once I found it a bit difficult to keep track at times. I'm no Morse but I had fun trying to figure out all the clues and try to solve the case, I particularly enjoyed the hidden code in the letter, how exciting! I really liked this book but for mysteries and cases I think I work much better visually. From this book I learnt 2 new words: obsequious and lugubrious.
