The Bad Quarto is a detective story set in Cambridge involving wonderfully arcane Cambridge customs, mad university politics and a Shakespeare play. I finished it in one go and will certainly read it again some day.
Where the previous book, Debts of Dishonour, was a huge disappointment this is quality stuff. A great one for anglophiles, lovers of Shakespeare and the old-fashioned detective story where you can still gather information by buying the local bum a cup of tea even if he is on drugs now.
The only thing I didn't like was the hasty ending. I rather enjoyed the characters and could have done with a bit more wrap up time.
