Fringe plus chocolate plus Tin Cat Café equals a fun night out for anyone seeking something different from stand-up comedy or busking. Ten murder suspects are scattered throughout the café, ready for the audience – as free-ranging detectives – to interrogate and even sift through their bags in order to find out who murdered A.J Oak. Providing a delicious distraction are Tin Cat chef Guy Davies’s splendid delicacies (of the chocolate variety!) which provide even more reason to burn up the calories by exercising the grey matter.

Developed by Vanessa Baylen, the evening was meticulously planned with notebooks, a communal blackboard for sharing ideas, name tags for mingling with other ‘detectives’ and an open invitation to eavesdrop. Each suspect did a superb job of not only remaining in character for the entire evening but also making things (for this reviewer at least) as complicated as possible. The answer to the mystery will be revealed online at the end of the Adelaide season, which is rather like having the final three rows of chocolate being taken away – enjoyably frustrating but something to look forward to later. Tin Cat Cafe until March 16.
