Anne Was Hired by Peter to Sell a Condominium in San

Anne was hired by Peter to sell a condominium in San Francisco.The asking price for the modest two-bedroom unit was $2,300,000.Peter told Anne he would go as low as $2,100,000,but no lower,but that she should try to get as high a price as possible.If he couldn't get that much for it,he said he would use it as rental property.A good friend of Anne's was in the market for a two-bedroom condominium in San Francisco.In fact,this friend had come to Anne to help her find a place and negotiate for it.Anne's friend said that she could absolutely not spend more than $2,000,000.When Peter hired Anne to sell his condominium,Anne told her friend about it and the asking price.Anne told her friend,"Don't even bother.He won't go below $2,100,000,that is his bottom price." Anne's friend accepted that.Anne then proposed to her friend that they go in together,with Anne fronting some money through her friend,but not having Anne's name on the contract as purchaser.Before they could work out the details,Anne's friend received a raise and decided to buy the condominium.Anne negotiated a price of $2,100,000 on Peter's behalf.Peter later found out that Anne had told her friend about his bottom price,and about the plan for Anne to help buy the house.What claims,if any,does Peter have?
