 Once Norreis reached the king he was converted to Baldwin 's side , perhaps because of the latter 's appointment of Norreis as the cellarer of Christ Church while the pair were at the king 's court . The monks resisted this appointment , and in September they appealed to the papacy , arguing that the appointment was against the Benedictine Rule . They also captured and held Norreis in custody , telling anyone who enquired after him that he was sick . Norreis escaped in early 1188 by travelling through the sewer and fled to the safety of the archbishop , who was then at Otford . In a mocking reference to his escape route , Norreis was occasionally known as Roger Cloacarius or " Roger the Drain @-@ Cleaner " . Baldwin then tried to have Norreis installed as prior at Christ Church 's dependent priory of St Martin 's , Dover , but the appointment was never confirmed .
