The man's name was Clayton Dawson. The Cool-Lam Agency was so well known that he'd come from Denver for help on a highly confidential matter...

After adjusting to the fact that "Cool" was a woman (a "Big Bertha" as it turned out) and "Lam" looked like he couldn't hurt a fly (an outrageous deceit), Dawson shelled out a fat retainer and put his cards on the table.

The question was: Were they from a marked deck?
