Spider's Web is a novelization by Charles Osborne of the 1954 play of the same name by crime fiction writer Agatha Christie and was first published in the UK by HarperCollins in September 2000 and on November 11, 2000, in the US by St. Martin's Press.

Like those books, the novelization is a straightforward transfer of the stage lines and directions of Christie's script into a written narrative.

Osborne chose not to add characters, lines or scenes which would alter in any substantial way what had been presented on the stage although minor amendments were made to produce suitable chapter endings.

There are three guests in the house – her godfather Sir Rowland "Roly" Delahaye, Hugo Birch and a young man named Jeremy Warrender.

Later when Pippa returns from school she indulges herself in exploring parts of the manor house with Jeremy and reveals a secret passage.

Meanwhile, Clarissa is confronted by a visitor to the house, a man named Oliver Costello, who happens to be Pippa's mother's second husband as well as a drug addict.

That was why Costello approached Clarissa, thinking that she was Mrs Brown, the owner of the manor house and the partner in his antique shop business.
