In an action by a real estate broker for a commission for procuring a purchaser for a farm, who at first stated to the owner that he would not buy it, but who, on the same day, offered to take it on the terms agreed on, an instruction that he would have no right to return and offer to take the farm for the mere purpose of collecting a commission from defendant, was erroneous, as suggesting a conspiracy between the broker and the purchaser. Bailee v. McMurray, 113 Mo. App. 253, 88 S. W. 157.
