Her friend Danny Bond had been arrested for the 'Chelsea Robbery', but she proclaims his innocence. When Rollison meets Danny he is both hostile and states he doesn't want anything to do with Sheila. Thus begins a mystery which inevitable sees Rollison drawn in and put in danger – but this time from a very unusual source.
