 Sillem's analysis of the Lincolnshire plea rolls in 1936 was the first major study of de Cantilupe's murder.She highlighted how the case not only demonstrated contemporary approaches to crime and petty treason but also provided a wealth of information on the more mundane aspects of society, such as the organisation of a late-14th century magnatial household.Her conclusion—that the murder was planned by Maud and Kydale with Paynel's assistance—led her to propose a pre-existing romantic connection between the first two, but she was unable to establish a motive for Paynel's involvement.
