How to Solve Your Own Murder

In the present, Mr. Gordon says Frances wanted Annie to stay at Gravesdown Hall. The will’s reading will be in the morning. He warns her to look out for Elva. In the taxi, Annie calls her mother with news about Frances’s death, having forgotten about Laura’s exhibition at the Tate happening that night. Laura asks Annie to get the file Frances had on Sam Arlington, Annie’s father. The driver, Reggie Crane, has been eavesdropping and tells Annie he had a relationship with Laura when he was younger and is Detective Crane’s father. Annie remembers the secretary saying Frances was horrible to the entire Crane family.

Archie Foyle is inside the manor with his daughter Beth, who cooked for Frances. Annie goes into the room where Frances’s old filing cabinets are. The files are organized by indiscretions, not names. She finds her father’s under “I” for infidelity and takes it. She removes other files containing names she recognizes and takes them upstairs. She looks in the bedrooms to choose one and finds Elva and Oliver have taken the biggest ones. She looks in Elva’s blazer pockets and finds the Post-It notes Elva tore down from Frances’s murder investigation board. She then finds a comfortable room and is surprised to find her bag already there.
