A real-life ladies' detective agency

Not in Botswana, but Zambia.

They say the majority of their detectives are women because they are trying to redress the "traditional gender imbalance in Zambian society"... but they also admit that women are simply better at the job.

"Ladies are a very valuable tool," says Edmond Lifwekelo, the agency's director of investigations.

"We discovered that most of our cases, especially marital cases which involve surveillance, are handled very well with women there. We had a problem some time back. When you are doing surveillance in a bar or a nightclub and you put a man there, he starts drinking, he gets drunk and he can easily be compromised.

"In our own experience we've found that it's quite different with ladies. She'll just have a coke or a tonic. They are very disciplined."
