At the very bottom lay the originals of three documents: the nominee shareholding agreement, the $150 million transfer voucher, and the letter my mother wrote before she passed.

The paper had yellowed, but her elegant handwriting remained sharp:

*Joanna, my biggest regret was letting my partner know my trump card. You must remember: a trump card is only revealed when it will deal the most damage. Strike only when it will be fatal.*

I pressed the letter to my chest and closed my eyes.

*Mom, I'm in so much pain.*

*Painful enough to finally play my hand.*
