The intrigue carried on by a foreigner of obstinate temper with local persons is of the following form:--"If after killing his own master, he comes to me, then I will secure these two objects, the destruction of my enemy and the acquisition of the enemy's lands; or else my enemy kills him, with the consequence that the partisans of the relations killed, and other persons who are equally guilty and are therefore apprehensive of similar punishment to themselves will perturb my enemy's peace when my enemy has no friends to count; or when my enemy falls to suspect any other person who is equally guilty, I shall be able to cause the death of this or that officer under my enemy's own command."
