The first step which the ministers took was to send Marlborough to the Tower. He was by far the most formidable of all the accused persons; and that he had held a traitorous correspondence with Saint Germains was a fact which, whether Young were perjured or not, the Queen and her chief advisers knew to be true. One of the Clerks of the Council and several messengers were sent down to Bromley with a warrant from Nottingham. Sprat was taken into custody. All the apartments in which it could reasonably be supposed that he would have hidden an important document were searched, the library, the diningroom, the drawingroom, the bedchamber, and the adjacent closets. His papers were strictly examined. Much food prose was found, and probably some bad verse, but no treason. The messengers pried into every flowerpot that they could find, but to no purpose. It never occurred to them to look into the room in which Blackhead had hidden the Association: for that room was near the offices occupied by the servants, and was little used by the Bishop and his family. The officers returned to London with their prisoner, but without the document which, if it had been found, might have been fatal to him.
Late at night he was brought to Westminster, and was suffered to sleep at his deanery. All his bookcases and drawers were examined; and sentinels were posted at the door of his bedchamber, but with strict orders to behave civilly and not to disturb the family.
