Showing The Bad Quarto by Jill Paton Walsh

Another foolhardy Cambridge college-climber has died attempting Harding's Folly. This time it's John Talentire, one of the brightest young dons at St Agatha's, and the verdict is accident, compounded by idiocy.

But Imogen Quy - her name rhymes with 'why' - can't help wondering how such a clever young man died so stupidly.

And when a wildly eccentric production of Hamlet is interrupted by a murder accusation, Imogen has to look into it, uncovering more crime than she expected.
