 Catesby waited for Percy's return from the north, before making his decision. He thought the letter too vague to constitute any meaningful threat to the plan, and decided to forge ahead. As Fawkes made a final check on the gunpowder, other conspirators took up their positions in the Midlands. Salisbury, already aware of certain stirrings before he received the letter, did not yet know the exact nature of the plot or who exactly was involved. He elected to wait, to see how events unfolded. On 3 November, Catesby met with Wintour and Percy in London. Although the nature of their discussion is unknown, Fraser theorises that some adjustment of their plan to abduct Princess Elizabeth may have occurred, as later accounts told how Percy had been seen at the Duke of York's lodgings, enquiring as to the movements of the king's daughter. Nicholls mentions that a week earlier — on the same day that Monteagle received his letter — Catesby was at White Webbs with Fawkes, to discuss kidnapping Prince Henry rather than Princess Elizabeth.
