Your Family are very low better not have them shewn up to ridicule in Harriette Wilson’s memoirs with your neices [sic] affecting love letters to the handsome young man she seduced and then applied to him for means to destroy the infant in her bosom useless to deny this or cry “fie” for I have the letters in my possession – as well be quiet and oblige a lady you are growing rich I have spent all my money in furnishing my home and paying my debts will you do an act of Gallantry and send me 100 £? If you do I shall not be ungrateful – or you may publish this letter like Edward Ellice but verily friend Adolphus we are none of us perfect have all our little sly intrigues either in the neighbourhood of the new Road or elsewhere and I might say to you in the words of Don Quixote to Sancho – “verily friend Sancho the more thou stireth it the more it will stink ---- once more will you be my favourite and a noble man[?] of Gallantry – if so forward me 100 £ trust to my gratitude – Brougham I am sure would say you might do so safely,, - & sign yourself The Dauphin for fun – but you must be quick about it Yours truly [?]- because you are witty Henriette Rochfort
