Take a look at the hints below for guidance.
Hint 1
Who is Thomas of Llewenor and what is his relationship to Graves? Read the letter Graves wrote to King Richard.
Hint 2
Thomas is Graves’ bastard son, who is legitimised at Graves’ request. Do we know what Thomas looked like? Study the tapestry photo.
Hint 3
The tapestry shows a nobleman in a red 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 Thomas’ coat-of-arms. Next, is there any incident in which Thomas might have killed Graves?
Hint 4
In the translation of Henry’s confession to Hermann, Henry notes Thomas also shot at Graves with a bow and arrow during the hunting accident in summer 1381. Henry takes the blame, but Thomas’ arrow may have been the one to have struck Graves. Does this wound sound familiar?
Hint 5
Notes on the photo of Graves’ skeleton show Graves suffered a narrow chest wound. Would Thomas have a motive to kill Graves? Follow the hints for Accessing Gisele’s UoSE Email if you are stuck.
Hint 6
Graves’ letter mentions Harcourt believes Thomas is a fraud, and not Graves’ son, based on rumours he heard at Westminster. Can this be corroborated?
Hint 7
A piece of correspondence from Westminster states the Duke of Lancaster had sent some imposter to antagonize Graves. This must be Thomas, pretending to be Graves’ son to take the barony with the Duke’s backing. Thomas’ lack of relation to Graves is confirmed in the modern day via DNA testing. Thomas lied about his parentage—he may have been willing to kill Robert and see if Henry would take the blame in order to become the next Baron Cherwell. If Graves died in 1381 from the chest wound, and Henry’s confession was misinformed, Thomas 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.
