Mark Perlstrom is no stranger to money laundering, drug smuggling and crooked firms.

In the late 1980s he started working for HM Customs and was quickly thrown in the deep end, joining Operation C-Chase, an undercover investigation that penetrated Pablo Escobar's mighty Medellin cartel, brought down the corrupt BCCI bank and stopped London's gangs from moving their ill-gotten gains around the capital. As part of the Uniforms - the new, secret, anti-money-laundering squad - high-speed car chases, bugging homes and spying on targets was day-to-day business. Told by a true insider and revealing never-before-told-secrets of the industry, India Uniform Nine lays bare the intense rivalry between crime-fighting organisations and how that leads to corruption, chaos and some scarcely believable antics in the covert world. And how Mark's own operation was nearly scuppered by a US Customs bungle.
