Sotheby's says an unpublished work by the teenage Charlotte Bronte could sell for 300,000 pounds ($482,000) at an auction next month

The auction house says "The Young Men's Magazine, Number 2" is dated August 1830, when the writer was 14.

The mini-magazine, measuring 1.4 inches by 2.4 inches (35mm by 61mm), contains a tale of murder and madness set in the imaginary world of Glass Town.

Sotheby's book specialist Gabriel Heaton said it "provides a rare and intimate insight into one of history's great literary minds."

He said it includes a foretaste of a famous scene in Bronte's "Jane Eyre" _ "when Bertha, Mr. Rochester's insane wife, seeks revenge by setting fire to the bed curtains in her husband's chamber."

The manuscript will be sold Dec. 15 in London.
