After this date nothing farther was heard from the traveller, no more of his bills were presented for payment at Tripoli, and Mr. Warrington becoming uneasy prevailed on the Pasha to have inquiries made respecting him. Messengers were accordingly despatched southward in various directions, one of whom on his return in the spring of 1827 brought an account that the Christian had been murdered soon after leaving Tombuctoo, by a party despatched from that place for the purpose. This statement was confirmed by all the other messengers on their return, and it was confidently repeated in a long article on the subject published in a Paris Journal, which gave the Prime Minister of Tripoli as authority. The other caravans and travellers however from the South contradicted these reports, and Hassuna D'Ghies on being questioned respecting the account driven in the Paris Journal, denied that he had supplied such information and asserted his total disbelief of the story. These and other circumstances induced Mr. Warrington to suspect that the Pasha or his Minister had for some interested motive suppressed Laing's communications; at his request therefore, the Commander of the British squadron in the Mediterranean sent a ship of war to Tripoli to give Yusuf notice that as the traveller had proceeded to the interior under his protection, he should hold him responsible for his safety, or at least for the delivery of his property and papers. This intimation was certainly of a most unreasonable character; the Pasha however could only exert himself to avert the threatened evil, by endeavoring to discover the traveller and at all events to disprove any unfair dealings or bad intentions on his own part with regard to him. All doubts respecting the fate of the British traveller were however dispelled by the return to Tripoli of the servant who had accompanied him; from the statements of this man it was clearly ascertained, that the unfortunate Laing had been murdered in his sleep by his Arab conductor Burbushi on the third night after their departure from Tombuctoo, that is on the 25th of September 1826. Some time after receiving this melancholy news, the British Consul was induced to believe that papers which were sent by his son-in-law from Tombuctoo, had actually arrived in Tripoli; and in the course of the investigations which he made in consequence, a suspicion was awakened in his mind that they had been secreted by Hassuna D'Ghies, in order to conceal some gross treachery or misconduct on his part. Under this impression Mr. Warrington urged the Pasha to have the papers secured, and not being satisfied with the means used for the purpose, he finally struck his flag, and declared that all official intercourse between himself and the Government of Tripoli, would be suspended until they were produced.
