So I am watching the WW for the umpteenth time (it's my stand by 'get me through a period of lots of flights and train journeys' viewing), I'm sure I know all the plots and probably most of the dialogue but one thing still baffles me....
...how did they catch the guy who gave the signal to the two gunmen at Rosslyn (In the Shadow of Two Gunmen)? Gina has told them right after the shooting that there was a signal, the third guy, we get told that the two shooters had been taken down and killed within seconds of the attack but as far as I can tell they NEVER BLOODY EXPLAIN HOW THEY FOUND THE THIRD GUY WHO GAVE THE SIGNAL.
Or have I missed something completely...
