The Code of Flesh (BBC Audio Exclusive).

Audio  Released this week, Andrew Lane's The Code of Flesh is a sequel to his The Scent of Blood from last year.  Reporter James MacFarlane from the previous story is in 1890s Cardiff investigating "anaesthesia frolics" in which a doctor demonstrates the use of ethers on invited guests, some of whom disappear shortly afterwards.  The Doctor's also on the case (which is presumably why Torchwood's steering well clear) and hijinks similar to the previous audio ensue.  It's fine.  It's more of an atmospheric piece than the previous story with a conclusion which requires a fair amount of lamp-shading in the dialogue by way of justification, although it does have an interesting way of tying into the Time War.  It feels like less of a novelty than the previous story, although Dan Starkey's equally impeccable reading keeps it listenable.

Placement:  Somewhere at the start of the Time War.
