Shannon's good friend and retired tech billionaire, Raphael Nash, is loving his new retired life but he can't stay unoccupied for too long. He's started the Marigold Foundation that helps fund small companies and individuals who do humanitarian work around the world. It's an exciting time in Lighthouse Cove as Raphael hosts the first ever global conference inviting big thinkers from every area of industry to give presentations on eco-living.
Raphael's old business partner arrives in town with a grudge and a plan to steal him away from his important new passion project. Shannon knows her friend has no intention of giving up Marigold and is proud of Raphael for sticking to his guns. But when his former associate winds up dead, all signs point to Raphael.
It's up to Shannon to hammer out the details of the murder before her friend gets pinned for the crime...
Hammer Construction has been given their most challenging project yet, Raphael Nash would like them to completely renovate his farmhouse, and a barn and lay the foundation for another barn in less than eight months and then in less than a week raise a barn on the foundation using eco products - whilst a global eco conference is happening on the site, Shannon and her two foremen (well one foreman and a forewoman) take a deep breath and say they can do it, and they get everything ready a good while before the conference is due to start (including a large concrete tower that will house plants and have louvred windows that are solar powered). The only thing Shannon is now worried about is the barn raising, never having done anything like that before, but one of her staff has friends in Pennsylvania and so he headed over there to take part in and discuss how to do a barn raising. So far so good, but at the opening evening Shannon and Mac witness Raphael's prior business partner having various arguments, including a very heated one with Raphael himself, but no one expects to find the man well and truly dead under that beams etc for the barn.
Now Shannon and Mac have been drafted in by Raphael to find out what happened as all finger, police wise, seem to be pointed at him (even though Eric the police chief can't believe it but he has to follow where the clues lead, now all Shannon, her friends and staff want is to have everything sorted so life can get back to normal!
