He is a record collector - a connoisseur of vinyl, hunting out rare and elusive LPs. His business card describes him as the "Vinyl Detective" and some people take this more literally than others.
Like the beautiful, mysterious woman who wants to pay him a large sum of money to find a priceless lost recording - on behalf of an extremely wealthy (and rather sinister) shadowy client.
Given that he's just about to run out of cat biscuits, this gets our hero's full attention. So begins a painful and dangerous odyssey in search of the rarest jazz record of them all.
