Take a look at the hints below for guidance.
Hint 1
Henry Graves is the son of Robert Graves. Do we know what Henry looked like? Study the tapestry photo.
Hint 2
The tapestry shows a nobleman in a blue-and-black tunic. Friar Hermann’s song/poem mentions Graves sat in the centre with his two sons on either side, and the Cherwell Castle guidebook proves the tunic pattern is Henry’s coat-of-arms. Next, is there any incident in which Henry might have killed Graves, even by accident?
Hint 3
In the translation of his confession to Hermann, Henry admits to shooting his father with a bow and arrow during a hunting accident in summer 1381. He doesn’t have proof he fired the arrow that hit Graves, but is convinced he is guilty. Does this wound sound familiar?
Hint 4
Notes on the photo of Graves’ skeleton show Graves suffered a narrow chest wound. If Graves died in 1381 from the chest wound, and Henry’s confession is true, Henry is the killer. If you’ve covered all bases and you’re still stuck, please follow the hint section for The Final Hints to gradually reveal the answer to this case.
