his concern about a letter from Taylor with a threat from Mr Burwood and the potential ransacking of Lord Burlington's evidences; Sir William's intentions in this affair to possibly inform Lord Thanet; his fear that the value of Lord Burlington's estate may be exposed to the public by the investigations of these men (CS1/225/1);
the affair at court concerning the Earl of Thanet, Duke of Beaufort and Earl of Oxford (CS1/225/2);
the poor condition of the the hall and offices at Bolton adjoining and the crumbling walls and lack of lodging aside from the room used by Lord Burlington and Signor Senesino (CS1/225/3).
