Authors Philip Craig and William Tapply join together with their heroes J.W. Jackson and Brady Coyne to create a pleasant mystery set on Martha's Vineyard. Coyne has come to the island to advise his client Sarah Fairchild as to whether to sell her valuable beachfront property to golf course developers or environmentalists. Sarah is in precarious health and feels as if she needs to make this decision quickly. J.W. has been commissioned to find Katherine Bannerman who left her husband, came the island and then disappeared. When not involved in business, however, the two friends join forces to enter the fishing derby, which is a big event on Martha's Vineyard. Also J.W. is helping his two young children build a treehouse. Threats are made against J.W. and Brady, and Jackson's wife Zee has her tires slashed while at work. They work together trying to find out who is at the bottom of all of this. I wondered how the two authors would work together on this joint effort and they used the format of each one writing every other chapter, which features his hero. This is a pleasant book and an enjoyable read but, disappointingly the murderer was too easy to spot. The two main characters worked well together and would be a good match in future books.
