The Affair at the Semiramis Hotel

A young, wealthy vagabond English man, Calladine, whom Ricardo knew before, hastily comes to Ricardo's London home in the morning, while Hanaud happens to be visiting. Calladine, very agitated, still dressed formally as for an evening ball, tells his disturbing story- He had gone to a costume party that night in a hotel ballroom, met a beautiful young woman, Joan Carew, with whom he danced, dined, and talked. While dancing, Joan's eyes fixed upon a stout costumed lady, obviously wealthy. Calladine was puzzled, but didn't ask why the fascination with that woman. Joan and Calladine leave the party and Joan runs off at 1:30am. A few hours later, Joan appears at Calladine's apartment door, very distressed.
