Nadine owns two houses overlooking the Grand Sports Stadium. In 2001, Nadine leased one of the houses for a term of 15 years to Babu, a soccer fan who wanted to be able to watch soccer matches from the veranda overlooking the stadium. Nadine began to live in the second house. In January, 2013, Nadine made an agreement with Chris to let her own house for a week in February while she was away overseas, so that Chris could view the Melanesian Cup, which was to be held in the stadium that month. Chris paid Nadine $200 in advance. Just before the match was to be held, the stadium was destroyed by fire and the match was cancelled. Discuss Chris's rights and obligations under the contract using relevant cases.
