come to light that Sessle and Hollaby's assurance business is in liquidation and the funds embezzled. Over their table, Tuppence counters that Doris did not murder the man, as very few women nowadays use hatpins. That suggests that a man not conversant with fashions committed the crime and tried to frame a woman. Tommy soon remembers that near the seventh hole on the course is a small hut, and the two talk about the possibility that the woman in brown could have been a man in disguise. This leads them to wonder which man. Linked to Tuppence's theory that the embezzler of the company was not Sessle but Hollaby and his son, they speculate that the woman was Hollaby Junior in disguise.

One week before, her household received a box of chocolates anonymously through the post. Not liking chocolates, she did not eat any, and consequently she was the only one who was not taken ill afterwards. The cause was arsenic poisoning and this is the third occurrence in the area of such a gift and its after-effects. What perturbs Miss Hargreaves is that the paper in which the chocolates were wrapped was re-used from a previous parcel sent to the Grange, evidenced by a small doodle of three intertwined fish that she drew on it. The poisoner is therefore someone in her own home. Miss Hargreaves is a rich heiress. She inherited her fortune from her aunt, the wealthy widow Lady Radclyffe. Lady Radclyffe had invited Lois
