DOPERUN

Thirty days. A trench coat. A shark who compounds every time you fly. Fiction — a numbers game, not a how-to.

• Buy what is marked CHEAP. Sell what is marked HOT.
• Every flight adds 8% to the note. Kill it early.
• Thieves take pocket cash. The bank does not get robbed.

You start with $2,000 and a $5,500 note. Coat holds 100.
