Cowboys and killers in Vegas.

Who would want to kill a clown?

Lucky O'Toole, chief problem solver for the Babylon Hotel, the primo property on the Las Vegas Strip, isn't in any mood to find out.

For one, it's New Year's Day and Lucky's birthday.

And she hasn't caught her breath after a chase to the death in Hong Kong and Macau.

Her French chef is pushing to set the wedding date.

Her former lover, wounded in the China chase, needs TLC.

A young woman, in town with the rodeo, shows up at her office with a secret that could blow the lid off Lucky's life as she knows it.

And Lucky's mother starts acting like the secret could be true.

Could it?

What if everything Lucky thought she knew about her family was built on a lie?

And why would someone kill a clown?
