There is one thing about The Emerald Tiger, by Barnaby Edwards, which is quite remarkable and superlative: the incidental music, by Howard Carter, is some of the best I can remember from any Who story ever. I see that Carter has done music and sound design for several other Big Finish stories, none of which I remember grabbing me as much; perhaps they just gave him his head for a change. Here's 40 seconds of a particularly thrilling passage.

As you can tell from the music, the setting is India, in 1926, and the Doctor and colleagues end up in an exciting chase by train, car and balloon of dubious Brits and a large telepathic tiger to a lost valley where mysterious things are afoot due to a local infusion of handwavium (not what it's actually called but you get the idea). All jolly good fun, with the trememndous energy of the music reflected in the performance of regulars and guest cast (who include Cherie Lunghi). ( )
