Thirteen to One — Jean Van Hamme

XIII survived the trip back to his childhood home. The Mongoose has finally been caught and is in a high-security jail. But there is still one piece of the puzzle missing, and when President Sheridan asks him to discover who the Number I is, the man now known as Jason McLane doesn't hesitate for long. His best chance: finding Kim Rowland wherever she may be hiding. But the Mongoose has powerful allies and won't stay locked up forever.
