The writer—Colonel Colin Campbell, living under a number of aliases including his <a href="/wiki/Pen_name" title="Pen name">pen name</a> "Richard Ames"—is joined by a beautiful and sophisticated lady, Gwendolyn Novak, who helps him flee to Luna with a <a href="/wiki/Bonsai" title="Bonsai">bonsai</a> maple and a would-be murderer ("Bill"). After escaping to the <a href="/wiki/Moon" title="Moon">Moon</a>, Gwen claims to have been present during the revolt described in <i><a href="/wiki/The_Moon_Is_a_Harsh_Mistress" title="The Moon Is a Harsh Mistress">The Moon Is a Harsh Mistress</a></i>. </p><p>Still pursued by assassins, Campbell and Novak are rescued by an organization known as the Time Corps under the leadership of <a href="/wiki/Lazarus_Long" title="Lazarus Long">Lazarus Long</a>. After giving Campbell a new foot to replace one lost in combat years before, the Time Corps attempts to recruit Campbell for a special mission. Accepting only on Gwen's account, Campbell agrees to assist a team to retrieve the decommissioned Mike, a sentient computer introduced in <i>The Moon Is a Harsh Mistress</i>. Engaged in frequent time-travel, the Time Corps has been responsible for changing various events in the past, creating an alternate universe with every time-line they disrupt. Mike's assistance is needed in order to accurately predict the conditions and following events in each of the new universes created. Campbell's frequent would-be assassins are revealed to be members of contemporary agencies also engaged in time manipulation who, for unknown reasons, do not want to see Mike rescued by the Time Corps. </p><p>During the mission, Gwen is grievously wounded and Campbell loses his foot again, though the Time Corps succeed in retrieving Mike. The story ends with Campbell talking into a recorder (presumably the source of the first-person narrative) reflecting on the mission and his relationship with Gwen. </p> <div class="mw-heading mw-heading2"><h2 id="Background">Background</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=The_Cat_Who_Walks_Through_Walls&action=edit&section=2" title="Edit section: Background"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><i>The Cat Who Walks Through Walls</i> may be regarded as part of Heinlein's multiverse series, or as a sequel to both <i><a href="/wiki/The_Number_of_the_Beast_(novel)" title="The Number of the Beast (novel)">The Number of the Beast</a></i><sup id="cite_ref-chained_1-0" class="reference"><a href="#cite_note-chained-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup class="reference nowrap"><span title="Page / location: 145">: 145 </span></sup> and <i>The Moon Is a Harsh Mistress.</i> During a meeting of the Council of the Time Scouts, representatives from every major time line and setting written by Heinlein appear, including <i><a href="/wiki/Glory_Road" title="Glory Road">Glory Road</a></i> and <i><a href="/wiki/Starship_Troopers" title="Starship Troopers">Starship Troopers</a></i>, and references are made to other authors' works as well. </p><p>The title of the book refers to a cat by the name of Pixel, who has an inexplicable tendency to be wherever the narrator happens to be (see <a href="/wiki/Schr%C3%B6dinger%27s_cat" title="Schrödinger's cat">Schrödinger's cat</a>).
