"Watson: trusty sidekick to Sherlock Holmes; loyal engineer who built Bell's first telephone; unstoppable super-computer that became reigning Jeopardy! champ; amiable techno-dweeb who, in the present day, is just looking for love. these four constant companions become one in this brilliantly witty, time-jumping, loving tribute (and cautionary tale) dedicated to the people--and machines--upon which we all depend."--Page 4 of cover.
