Complainant's agent executed an agreement in her name, without her authority, giving defendant the exclusive right to purchase or sell a farm for a period of one year for $20,000, and in case defendant did not exercise his right to purchase, but sold the property he was to receive two per cent. on the $20,000, and all the farm sold for above such sum as compensation for his services; defendant procured a prospective purchaser to whom he offered the farm for $20,000, but the purchaser declined to buy at that price, and subsequently made a contract with complainant to purchase the farm for $22,500; as soon as defendant discovered the purchaser was dealing direct with the owner, defendant filed his contract for record, claiming an option for $20,000, and refused to release the same unless he was paid $10,000. Held, that such act clouded the title and justified the purchaser's refusal to complete the sale, depriving defendant of the right to commissions. Woolf v. Sullivan, 224 I11. 509, 79 N. E. 646.
