Dead in the Water

The Stonebridge Regatta is looming. The town's annual face-off against neighbouring Meadowfield is usually a weekend filled with sunshine, laughter and camaraderie. This year is different. A week before the race, the body of Stonebridge team captain Matthew Henderson is found dead in the water. The police file his passing as a tragic accident however, his grieving widow disagrees and suspects foul play is involved. She enlists the help of Adam and Colin, the town's amateur (self-proclaimed) private detectives to unearth the truth.
Did Matthew simply slip and fall into the water, or is there more to his death below the surface?
