Doris mistakenly accused Peter's son, Steven, of negligently burning down her barn. Peter believed that his son was guilty of the wrong and that he, Peter, was personally liable for the damage, since Steven was only fifteen years old. Upon demand made by Doris, Peter paid Doris $25,000 for the damage to her barn. After making this payment, Peter learned that his son had not caused the burning of Doris' barn and was in no way responsible for its burning. Peter then sued Doris to recover the $25,000 he had paid her. Will he be successful?
