In October 2005, Black, the owner of the Grand Opera House, and Harvey entered into a written agreement to lease the opera house to Harvey for five years at a rental of $300,000 a year. Harvey engaged Day as manager of the theater at a salary of $1,175 per week plus 10 percent of the profits.

One of Day's duties was to determine the amounts of money taken in each night and, after deducting expenses, to divide the profits between Harvey and the manager of the particular attraction playing at the theater. In September 2010, Day went to Black and offered to rent the opera house from Black at a rental of $375,000 per year, whereupon Black entered into a lease with Day for five years at this figure.

When Harvey learned of and objected to this transaction, Day offered to assign the lease to him for $600,000 per year. Harvey refused and brought an appropriate action against Day. Should Harvey recover? If so, on what basis and to what relief is he entitled?
