Continuity mistake: The only letter that Alexander B. Cust really wrote himself is briefly shown when Poirot visits the office of the Twinkle Toes stocking company. The lowercase "R" is too high every time (meaning that the typewriter isn't perfect, a detail put in for realism). Yet all the close-ups of a typewriter progressing through the work on that letter, or any of the letters written on the same machine, show a perfectly aligned "r."
