Thornton fraudulently represented to Daye that he would obtain for her a new car to be used in Daye's business for $17,800 from Pennek Motor Company. Daye thereupon executed her personal check for $17,800 payable to the order of Pennek Motor Company and delivered the check to Thornton, who immediately delivered it to the motor company in payment of his own prior indebtedness. The motor company had no knowledge of the representations made by Thornton to Daye. Pennek Motor Company now brings an action on the check that was not paid against Daye, who defends on the ground of failure of consideration. Is Pennek subject to this defense? Explain.
