Africa, revenge, recorded on a tape for benefit of the other?

[moonlightmead.livejournal.com]

I suspect that when someone finds this, I shall say 'Oh, of course!', but I cannot find it at all. I don't know whether it's on the Circuit Archive, but it's definitely on the CD. The big climax at the end is that someone - Bodie, I think, but it could be the other way around, or possibly even Cowley - is presented with a tape which goes something like,

'Who are you, how did you get in?' (which is voice of bad guy)
Explanations; whichever it is - Doyle, I think? - is there to take revenge on bad stuff suffered by their partner, and is absolutely implacable and cool about it.
Threat of a very nasty revenge - I think being shot in the spine, but possibly elsewhere.
Sound of a shot, and human-in-pain noises, and he's presumably done it.

I also think that one of the lads - presumably Bodie - had taken off for Africa earlier in the story and Doyle had had to go tracking him down. This revenge scene on the tape is also in Africa, but it is being listened to back in Britain, after they have both returned.

Racking my brains over this one. I've been meaning to ask for a while, but I wanted to refer to it in a post and I still can't find it, waah.
