"The Kahler Files, book V - Maxwell's Silver Hammer Adrian Kahler is a psychologist turned detective. He has a Sherlock Holmes intellect, extrasensory perception, and an ability to manipulate computers that even Steve Jobs would envy. Iran is ready to launch a nuclear missile at Israel. The United States is counting on one of its fleet of secretly laser-armed surveillance satellites to surreptitiously destroy the missile as it launches, but the satellite that will ""watch"" Iran has yet to be deployed. Each laser requires a crystal of spectacular size and purity, and the NASA lab responsible for crystal production has suddenly begun to fail. Iranian agents are suspected of sabotage, but none can be found. The only scientist who has ever succeeded in growing the needed crystals claims to have no understanding of what has gone wrong, but Kahler suspects that he is hiding a dark secret. It's up to Kahler and his team to defeat the agents working against them, solve the mystery, and get crystal production back on track. The launch window is closing. Time is running out. "
