Sounds like you need to discover Clive Cussler’s Dirk Pitt novels. Don’t bother with the latter ones, written by anyone willing to have a go, stick to the early ones: “Sahara”, “Inca Gold”, “Raise the Titanic” etc. Ok, they are a bit predictable, & a but James Bond, but they are well written & the plots are good fun. Perfect for half an hours daydreaming until your train gets in.
If you want the best then there is only one Frederick Forsyth. Start with “Day of the Jacksl”. But bare with it though. Forsyth spends a lot of time & effort setting the scene & the characters. The attention to detail is excellent though, &, bar one or two, I’ve enjoyed everything I’ve read of his.
