The Victorian medical sitcom continues with a mixture of quackery, crossdressing and insanity. The last of these follows “alienist” William (Mathew Baynton) who is dealing with a patient (Jamie Demetriou) who is under the delusion that he is a French noble. In order to restore him to sanity, William proposes staging a fake trial in order to prove that he is not a noble. Meanwhile, surgeon Robert (Rory Kinnear) tries to woo a wealthy female patron; his wife Caroline (Lydia Leonard) tries to sneak into a men’s-only medical gathering; and in-debt dentist John (Tom Basden) considers do something beneath him in order to solve his financial woes. Quacks is on BBC Two at 22.00. The entire series is available now on BBC iPlayer.
