What is the name of Jonathan Ainsley's company in To Be the Best by Barbara Taylor Bradford?

To Be the Best is the third book in Barbara Taylor Bradford's Harte Family Saga, which follows Paula McGill O'Neill, head of the family's empire and granddaughter of Emma Harte (the original heroine of the first book in the series, A Woman Of Substance). 
In the book, Paula meets with Jack Figg, the operator of a large British security and private investigating company to discuss their knowledge of Jonathan Ainsley. Paul states that Jonathan has made his home in Hong Kong after departing England twelve years earlier and that he owns a company called Janus and Janus Holdings. Paula is unsure of the nature of the company, although she suspects it is related to real estate dealings.
With this information in mind, Figg agrees to have Ainsley watched, and Paula demands that Figg have a report to her in five days, claiming that she needed the scoop on Ainsley "five years ago."
