Moroccan Traffic [EPUB ebook] 
Send a Fax to the Kasbah

The Chairman of Kingsley Conglomerates is conducting negotiations, which are both difficult and somewhat dubious, in Morocco. He is accompanied by executive secretary Wendy Helmann. However, there are soon distractions when unorthodox Rita Geddes appears on the scene. Wendy discovers that there is much more at stake than the supposed negotiations, and finds herself at the centre of kidnappings, murder, and industrial espionage. Explosions, a car chase across the High Atlas out of Marrakesh and much more follows. Of course, the prior arrival of portrait painter Johnson Johnson is in many ways fortuitous, but he has some ghosts of his own to lay.
