SF which pushes the possibility of a ""self-activating, problem-seeking computer with....mechanisms analogous to those of a human being"" about as far as possible. Mike the Angel, a specialist, is recalled to duty to transport ""Snookums"" to an area where its mechanical brain will not be able to destroy matter. Deaths aboard the craft, Snookums' exposure to religion, attempts on Mike's life, mechanical troubles -- and Snookums' collapse wind up a pre-&-posterous yarn.
