Datchet Diamonds - Richard Marsh

Oh dear! The Duchess of Datchet's diamonds, worth a quarter of a million pounds, have been stolen. Just as Mr. Paxton, a ne'er do well gambler planning to leave the country to escape his losses, reads this news item on a train, he overhears, in the next compartment, the actual thief boasting of his accomplishment. Then, when he arrives at his hotel and opens his Gladstone bag, he finds the bag is not his -- and it contains the spoils of the robbery! Will our hero take them directly to the magistrate and tell all he knows? Or will things take another turn, leading to brigands, danger, and possibly romance? - Summary by Jacquerie
