I have always thought my John Le Carré days were behind me, but his 1993 espionage novel "The Night Manager" pulled me back in again - and its BBC dramatisation is even better. It's a whole 346 minutes of the most intense on-the-edge-of-your-seat viewing, which means you have to be retired to have the time to watch it all in one sitting bceause you won't be able to stop.
All I could find on YouTube is the above audiobook. If you want to watch the gripping BBC dramatisation, you may have to visit your local Vinnies shop, which is where I found my 6-episode-DVD, all for a $2-gold coin.
