The Plein Air Chronicles Book One: The Tuesday Night Painters

This is the story of a group of painters who start out to solve a murder mystery and end up starting a retreat center.  Oh yes, using the aid of a quirky spirit. Along the way they grow in compassion, courage, and confidence. They almost succeed in what they start out with.
 But they do find a lot more - a sisterhood they never knew they could have.

It is also the story of how a very unlikely start can lead to the cultivation of a great idea.

Finally, what is the mission of the spirit? Is it to solve her own murder? Or something greater?
