Color of Danger — Ruth J. Hartman

When Patience Sullyard finds a mysterious note tied to a pigeon's leg, her commissioned panorama at a falconry flies the coop. Instead of painting in hues of brown and beige, her focus shifts to saving a troubled stranger. Walter Bexley craves adventure from his boring life. Insinuating himself into Patience's problem by accompanying her to the falconry might be just the answer. Will the risk they take be worth the exhilaration, or will Patience and Walter discover the threat is too dangerous?
