It was precisely because Dumas knew that that he was heading to the scene on his own feet. He halted at a distance from which he could observe the whole situation from afar, however, and did not advance farther.
Instead, with his usual fearless grin on his face... he spread open a scroll that had appeared, unnoticed, in his hand.
“If I want my actors to show courage, I guess I should revise the plot a bit.”
Then, spotting the officer with the prosthetic hand — John — in the distance, he grinned from ear to ear.
“I’m not gonna let you end up as bit parts. ...It’s guys like you who ought to be heroes.”
Muttering to himself, he began to write a “story” on the scroll. A present to his favorite actors in place of a modest bouquet.
“...Musketeers, Masquerade.”
While even the actors themselves remained ignorant of what that story meant... the curtain was quietly but surely rising on the next act of the tragicomic play.
