Magic Bullets: The Perfect Medicine by Keith Jahans was at times a fascinating read and just as you were getting interested in the storyline, it tailed off and went off the boil. The storyline was an excellent one, that research carried out by one couple and then discounted because of the effect of the drugs main component causing cancer, was then used by another drug company who were close to success in developing the new drug. It was disappointing because it promised to be a really good read but in the end was only average.
