Mrs Havershaw

Mrs Havershaw is the woman Mr Green intended to take to his firm's annual dinner, but she fell down a staircase and broke both her legs, rendering her unable to go to the dinner. Mr Green took Nanny Piggins to the dinner instead. Nanny Piggins has been "cornered" by Mrs Havershaw and told about Mrs Havershaw's black dahlias. A quote from the first book describes Mrs Havershaw's and Nanny Piggins' conversation:

''"The last time Mrs Havershaw had cornered her, Nanny Piggins had thought she was going to slip into a coma. Mrs Havershaw had spent forty-five minutes droning on about her black dahlias. It was fifteen minutes before Nanny Piggins realised dahlias were flowers." ''

Mrs Havershaw has not made a direct appearance, but has been mentioned in the first book.
