Irene Grosvenor

In the novel A Pocket Full of Rye, Miss Irene Grosvenor is a competent, beautiful blonde secretary in Rex Fortescue's office. She was his personal secretary, but left Consolidated Investments Trust shortly after his death. She didn’t stay on as the personal secretary of Percival Fortescue, but was succeeded by a Mrs Hardcastle.

She lives at 14 Rushmoor Road, Muswell Hill.

When she was Rex's secretary, one of her duties was to make his tea and bring it to him. She did this as usual on the morning of his death, and was alarmed when he was taken ill just after drinking the tea.
