As day-trading became an American phenomenon, Mark Barton joined Brent Doonan's company, All-Tech. He first showed a lot of enthusiasm and potential, but soon all he amassed was a huge debt. He left All-Tech and opened a new secret account at another day-trading firm but was soon in over-his-head there as well, owing over six figures. He disappeared, seemingly for good, until he returned with an inexplicable rage and a shot-gun to back it up--killing nine and wounding a dozen, including Doonan. Both a personal catharsis and a quest for the truth, Brent Doonan tells the story of his horrifying attack and his arduous recovery.
