The Retirement — Stephen Donald Huff

A trusted agent in the employ of an untrustworthy corporation. He knows too much and he realizes this knowledge will soon necessitate his own liquidation. Will he retire in style to a lavish future, or will his employers violently consign his remains to an unmarked grave? He's tired of the rat race, and he has a plan for a fantastic exit. Sometimes, the rat gets the cheese and the trap springs empty.
