 Garnet spent much of 1604 on the move , although few details of his travels exist . At Easter he reportedly gave a mass at Twigmoor Hall , the house of John Wright . In November he was with Anne Vaux ( whose family he had been introduced to in summer 1586 ) at White Webbs near Enfield , renewing the vows given on the Feast of the Presentation of Our Lady . On 9 June 1605 , he was to be found in a room on Thames Street in London , with Robert Catesby . In the midst of what Garnet later recalled was a seemingly casual conversation , Catesby asked the priest about the morality of " killing innocents " . Garnet replied according to Catholic theology , that often , during war , innocents were killed alongside the enemy . According to Antonia Fraser , Garnet may have thought that Catesby 's request was to do with him possibly raising a regiment in Flanders .
