Frederick Crews published The Pooh Perplex in 1963 as a send-up of academic literary criticism, and it remains one of the sharpest tools in the genre-parody kit. Twelve essays, each mimicking a different critical school, each applied with deadpan sincerity to A.A. Milne's Hundred Acre Wood. Eeyore as Christ figure. Proustian Weltschmerz lurking in Piglet's existential dread. A Marxist reading that condemns the entire text for its conspicuous absence of the working class. The joke lands because Crews knew exactly how each critical mode operated — well enough to replicate it, which is the hardest kind of parody to write. The deeper joke, and the reason The Pooh Perplex still circulates in university syllabuses, is that the essays are strangely plausible. That is not accidental. Crews was demonstrating that the interpretive machinery of literary criticism can be applied to almost any text and generate something that sounds like argument. The target was never Pooh — it was the critical apparatus itself. That satirical precision is what separates the book from mere pastiche. The second letter recovers a different kind of gap: the pre-Paddington bear. Mary Plain, created by Welsh writer Gwynedd Rae in the 1930s and set in the bear pits of Berne, predates Michael Bond's Paddington by decades. She ran on Children's Hour and Jackanory and was the subject of more than a dozen stories. That she has largely vanished from the conversation about beloved fictional bears is a minor act of cultural forgetting worth correcting. There is a pattern here worth naming. Literary culture tends to canonize the work that arrived at the right moment for a particular generation and had the institutional backing to persist — a publisher, a TV slot, a tie-in. Paddington had all of those in abundance. Mary Plain had the stories and the airtime but not the staying power of merchandise and film adaptations. Crews' Pooh Perplex nearly vanished too, and was reissued decades after its first publication partly on the strength of academic word-of-mouth. What both letters are really doing is the same thing good readers always do: pushing back against the editorial frame, supplying the context the original piece omitted, and insisting that the map of the tradition is larger than the headline version. The Guardian's editorial evidently mentioned Paddington without Mary Plain, and praised Milne scholarship without The Pooh Perplex. Both corrections are earned. Letters pages, at their best, are the part of the newspaper where the readers are smarter than the editors — and this is one of those cases.
