Original, unpublished and meaningful letter by British official and Permanent Under-Secretary of State for the Colonies, Sir Robert William Hay, addressed with urgency to former secret agent in Spain and Portugal, Sir Charles Stuart de Rothesay, Scottish nobleman, and English ambassador to France (1815-1830); alerting Ambassador Charles Stuart of Hay’s arrival in Paris and his wish to ask him if he has “anything to communicate to me in regard to that Royal [Baron] Rousseau, The Barbary Consul”. Hay is in this letter preparing Stuart in order to investigate the situation around the death of explorer Alexander Gordon Laing in Africa. Under-Secretary for the Colonies, Sir R[obert] W.Hay, who had been informed about the situation around Laing’s missing Journals per private letter from the British Consul in Tripoli, Hanmer Warrington, announces his arrival in Paris to protest to the French government and advices ambassador Stuart:″I conclude that he [Baron Jean-Baptiste Rousseau] is by this time out of guarantiae, but I hope that by ensuing at Paris he will only get out of the frying Pan with the fire”. Hay continues: “I hope you will go with me (in case it be necessary) to the Minister, whoever he may be, in [?] Departement this ….were incredibly false for it. The French Govt. are really disposed & prosecute the Enquiry bon a fide. I think that same may acq…[….]…..on the other hand, if the French Govt. do not enter into y. enquiry with a good spirit, it will be in Rousseau’s …..to baffle me with the utmost facility in all our attempts to get at the truth. I spoke to Lord Aberdeen [George Hamilton-Gordon, 4th Earl of Aberdeen, Foreign Secretary for Prime Minister Wellington] on the day I left London, & he gave me full permission to conduct measures with you for the …of this affair. Yours very truly R.W.Hay”.
