Maxwell Haverstock, known as Max, is a former colleague of the victim, John Allen, in "Deep in Death", and at first he looks good for murder. When Beckett and Castle see him, however, the writer points out that "this guy couldn't throw a wet sponge off the roof, let alone a body". Max is clearly nervous about his interview with the police, but warms to his theme when discussing his dismissal and how he'll pay back those responsible.
