A totally secure meeting, in a totally secure laboratory, every attendee cleared and confirmed. How did two unknown gunmen suddenly appear, threatening twenty people with a powerful laser beam and viciously attacking the chief engineer? Evan Olsson hears the screams of victims and smells burning flesh as he pursues the criminals from the room only to stumble over his favorite security guard, dead in a pool of her own blood. The mysterious crime is revealed as part of a larger plot when a powerful laser is stolen by high-tech means. Evan and his FBI partner Matt discover an international conspiracy to attack L.A. infrastructure and murder global leaders. They reach the heart of the plot but find themselves trapped deep underground by the criminals as the conspiracy reaches its deadly conclusion. Death By Tech plunges Evan and Matt into a whirlpool of liaisons and betrayals as they seek bits of truth that can be trusted. Their work is undercut and placed in jeopardy by even their closest allies, who seem to have sinister agendas of their own. Evan's problems are compounded by shocking developments in his love life. He will need all his skill and luck to get through this case and regain his optimistic faith in the future. URNO BARTHEL is the pen name of ART CHESTER, a technologist and mystery writer.
