Garnet first appeared in front of the Privy Council on 13 February 1606. Present were John Popham, Edward Coke, Sir William Waad, and the Earls of Worcester, Northampton, Nottingham and Salisbury. Superficially, they treated him with respect, removing their hats and addressing him as "Mr Garnet", although they made fun of his relationship with Anne Vaux, claiming he was her lover, not her confessor. During his questioning he admitted some of his movements, and that he had received Catesby's letter on 6 November, but he denied being involved in the plot, whose members he did not name. Garnet was convinced that his captors were interested only in the failed scheme and believed he might be able to clear his name, but the councillors also asked him about the doctrine of equivocation. His own treatise on this topic, one of the "heretical, treasonable and damnable books" found amongst Francis Tresham's possessions, was laid on the council table before him. Although it condemned lying, Garnet's treatise supported the notion that when questioned, for instance, on the presence of a priest in his house, a Catholic might "securely in conscience" answer "No" if he had a "secret meaning reserved in his mind". The occasions on which a Catholic might legitimately use equivocation, he supposed, were limited, but such replies could be taken as an example of insincerity or deviousness—especially to the king's council, who may not have wanted to see Garnet prove his case. The council's view of equivocation was very different from Garnet's. In their eyes, it was simple deceit.
