Albert, Betty, and Carol own and operate the Roy Lumber Company, a limited liability partnership (LLP). Each contributed one-third of the capital, and they share equally in the profits and losses. Their LLP agreement provides that all purchases over $2,500 must be authorized in advance by two partners and that only Albert is authorized to draw checks. Unknown to Albert or Carol, Betty purchases on the firm's account a $5,500 diamond bracelet and a $5,000 forklift and orders $5,000 worth of logs, all from Doug, who operates a jewelry store and is engaged in various activities connected with the lumber business.

Before Betty made these purchases, Albert told Doug that Betty is not the log buyer. Albert refuses to pay Doug for Betty's purchases. Doug calls at the mill to collect, and Albert again refuses to pay him. Doug calls Albert an unprintable name, and Albert then punches Doug in the nose, knocking him out.

While Doug is lying unconscious on the ground, an employee of Roy Lumber Company negligently drops a log on Doug's leg, breaking three bones. The firm and the three partners are completely solvent. What are the rights of Doug against Roy Lumber Company, Albert, Betty, and Carol?
