Brian is in the business of buying and selling second hand motor vehicles. The vehicles are usually displayed at a large yard located along Langata Road in Nairobi. Brian also receives and sells cars on behalf of individual owners at a commission. Such cars are usually displayed at the same yard. At around 9:00 a.m. on 1^st May 2017, Alice went to Brian's yard and saw a car which she wanted to buy. The owner of the car, Oscar had left it with Brian with instructions that Brian was to obtain "good offers" but that he (Brian) was not to accept any offers without first consulting with Oscar.

Unfortunately, Oscar had inadvertently left the car's logbook in the car's glove compartment. Using this document, and holding himself out to be Oscar, Brian sold Oscar's car to Alice.

Alice paid the full purchase price in cash. She also obtained from Brian (who was pretending to be Oscar) the car's log book together with a duly executed transfer form. Alice did not, however, drive away the car on the day as she was travelling out of town. On the same day in the afternoon, Oscar came and took away his car, telling Brian that he had changed his mind and was no longer interested in selling it. Upon her return, Alice made several unsuccessful attempts to collect the car from Brian. She has now 'unearthed the truth' but is not sure what to do.

Identify and discuss the legal issues raised by the above pattern and advise each party of their redress, if any.
