Edmund Crispin, pseudonym of Bruce Montgomery is generally considered the last of the British high literate mystery writers. He wrote a series of mysteries starring Gervase Fen, Oxford don, highly intriguing in their own right as complicated mystery puzzlers, packed with engaging literary and musical allusions, plus quite a few wonderful parodies of academia scattered throughout.

In HOLY DISORDERS, a Regius Professor of Mathematics makes a brief, rather air-headed, appearance. In addition to reciting ``The Hunting of the Snark'', he mutters about calculus, and aids Fen by enumerating permutations.

I highly recomend all the fen novels as mysteries.
