New York- The secrets Manhattan madam Kristin Davis’ little black book are out, revealing the names of over 2,000 men who splashed thousands for a few hours with her.

Davis’ little black book, which has been obtained by the New York Daily News, contained the names and numbers of her customers.

The amount of business made by Davis comes down to more than 1.1 million dollars and provides a rare and tantalizing glimpse into the workings of a high-priced call girl ring that attracted the rich and powerful.

There are lawyers, doctors, venture capitalists, out-of-town businessmen and even a professional poker player – successful men who thought nothing of spending 1,000 dollars for an hour of illicit sex.

Davis, whose multimillion-dollar empire was recently dismantled, is rumoured to have the “biggest black book in America,” her lawyer has said.

A source said that the whole procedure of providing hookers was very sophisticated.

“She knew just how much she could get out of these guys. And if they booked an out call [off-site visit] for an hour, she would call them after 50 minutes to see if they wanted to run that credit card again,” the New York Daily News quoted the source, as saying.

When contacted, some of the men denied they had ever used Davis’ services.

“I called them but I never came to New York,” said one California man who was listed as booking two 1,000 dollars dates.

“Not me, man, no way,” said a john named Dominick who was criticized in the records as being too aggressive.

Davis outsourced her booking services so she could have calls answered 24 hours a day by operators around the world, and she relied on text messages to let girls know when a date was scheduled, the source revealed.
