The Prophecy of the Blood Born Earl by Hanna Hamilton

Loving her was his commitment to eternity a long time ago…

A trail of peculiar riddles is all Miss Cleo Wallace has to go on to find her father’s killer.

In their quest for answers, Cleo and Arthur have failed to see a most crucial detail: the answer has been right in front of them from the very beginning. An answer hidden in a painting that echoes through the ages, from thirteen hundred years ago…
