On March 1, Lucas called Craig on the telephone and offered to pay him $90,000 for a house and lot that Craig owned. Craig accepted the offer immediately on the telephone. Later in the same day, Lucas told Annabelle that if she would marry him, he would convey to her the property then owned by Craig that was the subject of the earlier agreement.
On March 2 Lucas called Penelope and offered her $16,000 if she would work for him for the year commencing March 15, and she agreed. Lucas and Annabelle were married on June 25.
By this time, Craig had refused to convey the house to Lucas. Thereafter, Lucas renounced his promise to convey the property to Annabelle. Penelope, who had been working for Lucas, was discharged without cause on July 5; Annabelle left Lucas and instituted divorce proceedings in July.
What rights, if any, have
(a) Lucas against Craig for his failure to convey the property;
(b) Annabelle against Lucas for failure to convey the house to her; and
(c) Penelope against Lucas for discharging her before the end of the agreed term of employment?
