The sealed manor.
Family members who cannot enter or leave.
An elderly lord, a young and beautiful current wife, and two equally young and vigorous sons—Arthur could imagine with just the heel of his foot what Lamit and Gilt were capable of doing that would tarnish the Doyle family's honor.
Especially after the old lord tumbled down the stairs, Lady Marian, Lamit, or even Gilt, or all three together, became even bolder.
This made the old lord sense that something was amiss.
Similarly, the three of them realized it as well.
That's why the old lord sought help from his "only son."
And that's why the old lord was murdered.
As for who did it?
It was still uncertain!
Lady Marian, Lamit, or Gilt all could be the culprits.
Having mostly figured out the situation, Arthur, without a change of expression, took out the ordinary letter without a signature and asked the old steward Vick about it.
"Have you seen this letter before?"
"Or, do you recognize the handwriting on it?"
