But regardless of how he might feel about it, his duties don't end with the completion of the plant; as a reserve officer in the Space Patrol, Mike is a logical replacement for the craft's unavoidably detained engineering officer.
Once into space, the Branchell—and Snookums—will offer everyone a harrowing, puzzling adventure whether they want it or not: the medical officer is murdered, and Snookums appears to be the culprit.
