Storming heaven / fallen gods (2 books)

The USA is under seige. Terrorist Henri Cazaux has been using large commercial aircraft to drop explosives on major US airports. When he unleashes a cargo of explosives on San Francisco airport, the national panic reaches all the way to the White House. The heat is on for DCC Bob Skinner, Scotland's most revered and, in some circles, most feared cop. His career hangs by a thread, as a recent illness gives his enemies a weapon to use against him. A body found in the detritus of a flood is identified as the hated brother whose existence he has kept hidden for years. On the crime front, an incendiary device destroys a valuable painting in the Royal Scottish Academy in Edinburgh. As Skinner and his team tackle these crises, his wife Sarah, left in America with their children to recover from the loss of her parents, finds comfort with an old college lover.
