The Madness is Illusory
"But it would be dangerous to search too earnestly for the allegorical in Titus Groan. It remains essentially a work of the closed imagination, in which a world parallel to our own is presented in almost paranoiac denseness of detail. But the madness is illusory, and control never falters. It is, if you like, a rich wine of fancy chilled by the intellect to just the right temperature. There is no really close relative to it in all our prose literature. It is uniquely brilliant, and we are right to call it a modern classic."
- Anthony Burgess on Titus Groan (1946) by Mervyn Peake
