Yes, he did! Garret Langham began as a secondary character in the Duchess series. (Duchess in Love, Fool for Love, A Wild Pursuit and Your Wicked Ways). Readers adored him and begged for more, so he continued into the Essex Sisters quartet (Much Ado About You, Kiss Me, Annabel, The Taming of the Duke and Pleasure for Pleasure). Mayne is so beloved, he even had his own fan club, the Bon Bons! Pleasure for Pleasure is Mayne’s story, in which he finds his own happily ever after.
Mayne-iacs will be happy to know that the Earl of Mayne and his wife, Josie, make appearances in two novellas! “A Midsummer Night’s Disgrace” which can be found in the Official Essex Sister Companion Guide. And then also in the novella “A Gentleman Never Tells“.
