On June 1, Smith contracted with Martin doing business as Martin Publishing Company to distribute Martin's newspapers and to account for the proceeds. As part of the contract, Smith agreed to furnish Martin a bond in the amount of $10,000 guaranteeing the payment of the proceeds.
At the time the contract was executed and the credit extended, the bond was not furnished, and no mention was made as to the prospective sureties. On July 1, Smith signed the bond with Black and Blue signing as sureties. The bond recited the awarding of the contract for distribution of the newspapers as consideration for the bond.
On December 1, payment was due from Smith to Martin the sum of $3,600 under the distributor's contract. Demand for payment was made, but Smith failed to make payment. As a result, Martin brought an appropriate action against Black and Blue to recover the $3,600. What result?
