...Watson and Crick build a model of DNA as a triple helix. Franklin immediately spots their major blunder...
...that separated us and began moving toward me. Fearing that in her hot anger she might strike me, I grabbed up the Pauling manuscript and hastily retreated toward the open door. My escape was blocked by Maurice [Wilkins], who, searching for me, had just then stuck his head through." Franklin shut the door on both men. "Walking down the passage," Watson continues, "I told Maurice how his unexpected appearance might have prevented Rosy from assaulting me. Slowly he assured me that this very well might have happened. Some months earlier she had made a similar lunge toward...
...began chatting. "Now that I need no longer merely imagine the emotional hell he had faced during the past two years," writes Watson, "he could treat me almost as a fellow collaborator rather than as a distant acquaintance." In the course of that conversation, Wilkins trotted out one of Franklin's images of the B form of DNA. Labeled Photograph 51, it was her best--and, writes Watson, "the instant I saw the picture my mouth fell open and my pulse began to race. The pattern was unbelievably simpler than those obtained previously. Moreover, the black cross of reflections which...

...wasn't just the clarity of Franklin's picture that excited Watson. It was also the fact that the pattern repeated itself every 34 angstroms (an angstrom is one ten-billionth of a meter). That gave Crick and Watson crucial information about the angles between bonded molecules. Even better, the image suggested that the bases attached to the backbone were neatly stacked one on top of the other...
