A rare Agatha Christie book has sold for £40,000, reports the Daily Mail. The high price is all because of the dust jacket, which carries an early image of Christie’s Belgian sleuth Hercule Poirot. The 1924 copy of Poirot Investigates was originally priced at 37 pence and the Daily Mail claims this is a record price for a Christie book. The jacket has Poirot leaning on a cane with his top hat tucked under his arm.

The person posing as Poirot looks rather like David Suchet, who played the detective in the popular TV series. The same little mustache, the same pompous pose.
