Cropland Farms, LLC, Hires Desiree to Act as Its Agent

Cropland Farms, LLC, hires Desiree to act as its agent to buy a certain tract of land from Ethan for $1,000 per acre. Cropland Farms does not want Ethan to know that it is the principal or that Desiree is its agent. Cropland Farms wants the land to test genetically modified seed products, and believes that Ethan may not sell the land for that purpose, or may demand a premium price if he knows that Cropland Farms is the buyer. Desiree makes the purchase, signing only her name to the contract as the buyer and not disclosing to Ethan the agency relationship. The transfer of the deed is to occur on June 1. Ethan learns of Cropland Farms's identity on May 15. Can Ethan legally refuse to deed the property on June 1? Explain.
