Globetrotter: The director of South African art at Bonhams has been lucky so far ...
Giles Peppiatt, director of South African art at Bonhams, values collections worth up to £150m across the world. He had a hair-raising experience in Nigeria.

How often do you travel?
I'm away every other week viewing collections of South African art. When the country was under the apartheid regime many people escaped, taking their expensive art with them. So the paintings are widely dispersed - I can be in Israel one week and Australia the next.
What do you do when you get there?
