Doctor in the House S09E01 - Thanks for the Memory

Duncan is working in St. Barnabas hospital, Sydney, under fearsome Professor Beaumont and alongside the Australian answer to Bingham, Maurice Griffin. Dick Stuart-Clark is admitted as an amnesia sufferer, though this is a ploy, as he skipped St Swithins having sold off oxygen cylinders and is wanted in Sydney for not paying his hotel bill. Duncan takes him to see Beaumont about a job but before any deal can be reached Griffin, whose patient Dick is, has shoved a syringe full of sedatives up his bottom and knocked him cold.
