Andy and Sue signed a valid written contract with Tin Men, Inc. (Tin) to install new siding on Blackacre. The contract stated in part, "If Andy can get disability insurance, Andy and Sue will pay Tin for the work." A week after signing the contract, Tin's crew arrived to install the siding. Andy objected because he had not obtained the insurance. Tin had Andy speak with an agent who took Andy's application for the insurance. Tin then immediately installed the siding. Andy's application for disability insurance was denied two weeks later. Andy suddenly died and Sue, by operation of law, became the sole owner of Blackacre and Woods. When Sue refused to payTin for the siding work, Tin sued for breach of their written contract. In defending the suit, Sue relied upon the contract's requirement that Andy obtain disability insurance. Will Tin's suit be successful? Please be sure to state your conclusion and all supporting arguments
