The Merchant and the Two Thieves

A merchant about sally forth on a business trip with his wares across the desert hired on two extra hands. Unbeknownst to him, both were thieves. They however caught on to each other very quickly. They confronted with one and other and came up with a devious plan to kill the merchant and steal his goods, but each had also devised a plan to double cross the other with poison. They exchanged their poisoned bread and water, which they both promptly ate and both promptly died. When the merchant saw this he took their stuff and proceeded on his way.
