The Mummy's Mirror — Dawn Aldridge Poore

With her three sisters finally wed, Miss Roxanne Sydney is free to pursue her favorite pastime: a mystery! Accompanied by Miss Flora Rowe, her poor but proper traveling companion, Roxanne is off to uncover the grandest of all mysteries, the land of Egypt. No sooner does she arrive than she meets wealthy, charming Lord Brydges, who invites her on a excursion up the Nile to search for ancient artifacts. But what Roxanne discovers is...Robert Lymond!

Once, she rented rooms to the dashing gentleman -- and very nearly surrendered to his charm. Now he's on the track of some precious lost papyri, and shocked at the sight of Roxanne in Lord Brydges' arms. Should he woo her, too? Or save her? For something decidedly odd is going on between the pyramids and the burning sands. And a missing mirror will soon turn the desert into perilous territory for a genteel detective in distress...and in danger of losing her heart!
