Key passages
“I found a writing case in her box of much too good a kind for a servant, and a blotting-paper pad with a lot of ink marks. When I put the pad before a mirror I made out an address written several times: ‘ Mr. J. Dangle, Laurel Lodge, Hopefield Avenue, Hendon.’”
Speedwell discovered a high-quality writing case and a blotting pad in Susan's room; by using a mirror, he read the address 'Mr. J. Dangle, Laurel Lodge, Hopefield Avenue, Hendon' from the ink impressions.
Speedwell's clever use of a mirror to read reversed writing reveals his investigative skill.
“I turn up this shoe, and I find here the very mark I was expecting. See for yourself. I think we may take it then, not only that Miss Merrill made the mark on the bank, and of course made it last night, but also that she was wearing these shoes when she made it.”
French examines the shoe and finds a yellowish clay mark on the outside of the right shoe, confirming that Joan Merrill made the footprint on the bank while wearing those shoes.
Forensic evidence links Joan to the scene at Wembley, deepening the mystery of her disappearance.
