Sloan Guaranty Trust has $12 million riding on the Chicken Tonight restaurant chain. Now the discovery that a mass poisoner has tampered with the "Chicken Mexicali" brings John Putnam Thatcher racing. Unless Thatcher can unravel the plot before it's too late, it will mean bankruptcy for Chicken Tonight ... and death for those who have unwittingly ordered murder to go.
