As the author of the new book about artist Joan Eardley, I appreciate letters to The Herald (March 21 and 22) regarding the headline about the many letters written by her to her friend Audrey Walker half a century ago.

One of your correspondents advocates exploring Eardley's work rather than her sexuality. If he had actually read my book, he would find that this is precisely what the book does. Its aim is to continue to investigate the riches of her work, and for such exploration there must be a rounded view of Eardley's (quite complex) character. Please read the book – and then say what you think.
