An intercepted Arabic e-mail, presumably to Al-Qaeda, from US-born Khalid Hassan, Muslim convert name of Steve Haas, son of a Yemeni immigrant, and ingredients found in his home suggest he planted a large bomb with nails somewhere in Manhattan. Even Jamie and his mentor, who shows him silly advertising suits make ideal crime covers, are kept in the dark as Frank convinces the mayor not to risk a panic by going public without specific information. Danny once helped Steve as terrified abuse victim but can't get through to him and suspects discrimination drove him to extremism. The key is provided by his family, as the ex of his brother, economics academic Adam Hassan, is detected by a 'random' roadblock, driving with their 9 year-old son Jacob. Written by KGF Vissers
