It Happened in Egypt

This is a novel book. Lord Ernest Borrow and Captain Anthony Fenton think they know a secret - a secret that could make them both rich. En route, they are sidetracked by Sir Marcus Antonius Lark, a woman who thinks she's Cleopatra reincarnate, a Gilded Rose of an American Heiress, and Mrs. Jones, a mysterious Irish woman with a past. Will they find the secret? Or will the trip up the Nile on the Enchantress Isis net them another discovery altogether?
