Firing Line. Number 41 in Series

Wild CIA Agent Ruby is getting too hot to handle, so fellow agent Remo is ordered by CURE to play the fireman. But friendship comes first, even to a Master of Sinanju, and these orders are enough to drive Remo over the edge - enough, in fact, for him to walk out of CURE entirely. But it's out of the frying pan and into the fire because Chiun, deferring to tradition, refuses to quit CURE. And they both know that soon he could be hot on Remo's tail.
Meanwhile, the heat's really on when New York fire-fighters suddenly take part in a walkout, prompting an arson gang to strike while the iron's hot. Unless they receive the ransom they demand, they'll turn the city into the biggest backyard barbecue in history .
