I remember long ago the BBC serialised the Day of the Triffids on the radio, and I used to sit listening to it on ye olde Rediffusion Box. I think more frightening than the subsequent TV series because you pictured what was going on in your head !!! Every time I hear a rattling noise even now (could be the car engine, a pen moving around in a drawer on a rolling ship, whatever ... ) ... I still think to myself ... 'Shit, a Triffid is coming !!!'With you on the Wyndham books.
