Jack Smith is an aging ex-convict with a string of convictions. He appears to have formed a Fagin-like relationship with a young boy, Leo Trotsky. Together, they are charged with stealing copper piping from a building and also of using this to cause actual bodily harm.

Ernest Richards details his dispute with Smith and the boy. Jeremy Parsons QC counters that Richards has served jail time for perjury. Sgt. Barnet discusses a mallet found, at the crime scene, containing the blood of Mrs. Richards.

Jack Smith gives his evidence and explains how he became Leo's guardian. Smith states Leo is 9-years-old and under the age of criminal responsibility. Jimmy Dobie is called on behalf of the defence but his evidence is patchy at best.
