Oak Parlour. The stains could have been cleaned up by a lady with a jug and basin and if anyone saw her, she would have been taken for the resident ghost. Satterthwaite accuses and Alix recognises Miss Glen as Monica Ford who called out Lord Charnley's name that night. The accused woman rushes out of Satterthwaite's house after confessing that she loved Hugo, and helped him with the murder, but he abandoned her soon after and is dead now.
