I would definitely buy another recording if the music cuold be excluded. The durgelike, hideous and penetrating music is hard on the ears, brain and detracts enormously from the enjoyment of the recording.
The narrators are superb.
This dramatization, in eight half-hour episodes, apparently dates from 1993. Rene Basilico's adaptation of the novel is skillful, though perhaps inevitably some important elements of the story (particularly to do with Pym's childhood) are omitted or only mentioned briefly. The production is good, and James Fox is excellent in the lead role. My only complaint is that some of the acting is at times a little cartoonish. It's as if the program came at a time of transition between an older, "stagey" style of voice acting and a modern, more naturalistic approach. Fortunately the problem is mostly confined to minor characters. Although this program is not quite up to the standard of the BBC's recent (superb) cycle of le Carre's Smiley novels, it is still effective and enjoyable overall. Here's hoping the BBC will release more le Carre dramatizations!
