Writes, prints and seethes: Queen of grammar in broadside against authors and publishers

Her irritation at bad grammar took Lynne Truss to the top of the literary bestseller lists with Eats, Shoots & Leaves: The Zero Tolerance Approach to Punctuation. Now, however, that irritation has turned to anger and disdain over a slew of parodies aimed at capitalising on her success.

In an outspoken attack on the wave of imitators who have spoofed the book's quirky title and cover design, Ms Truss said she did not know how publishers of such imitations "live with themselves".

Widening her criticism to include send-ups such as the recent Barry Trotter and Blarnia novels, she described most literary pastiches as "dreadful". Ms Truss's comments were prompted by a succession of books whose titles trade on the global success of her book, which has sold more than three million copies.

Among the best-known parodies are the straightforward spoof Eats, Shites & Leaves: Crap English and How to Use It, and Doctor Whom, a Doctor Who send-up about poor grammar acting as a catalyst for universal entropy. The latter is subtitled "E.T. Shoots and Leaves: The Zero Tolerance Approach to Parodication", and features a pun on Truss's own name in the guise of Time Lady companion Linnaeus Trout.

Even the Vegetarian Society has clambered on to the bandwagon, with a booklet entitled Eat Shoots and Leaves? More Interesting Cuisine from the Cordon Vert School.

Singling out the latest offender, Doctor Whom, Ms Truss said it "obviously has no merit whatsoever", but conceded that she hadn't read any recent parodies.

Adam Roberts, author of Dr Whom and a professor of literature at London University, said: "I'm impressed at her ability to intuit the dreadfulness of Dr Whom without having read it. It might be that the point of parody is not whether it's original but whether it's funny."
