"Mycroft got entangled in the case?"
The indifferent middle-aged man's face showed some astonishment.
He pulled out a piece of stationery and with a tremble of his hand, the soft paper seemed to become a stiff flying card, cutting a spinning arc and accurately appearing in front of Brian.
Brian's fingers precisely pinched the edge of the paper, flipping through it.
This was Mycroft's suicide confession:
I regret falling in love with a woman I shouldn't have loved.
For her, I did some disgusting things.
Stop the investigation.
The Mason couple, it was I who killed them.
His wife, through my lover, learned some things about me, pressured me to give her the rejuvenation procedure.
This is a risky medical technique not yet on the market, and the process is somewhat cruel, but for the sake of my lover's reputation, I chose to compromise and operate against the rules...
After the procedure, the effects were good, she got what she wanted.
