Great idea!<p>My path to solution:<p>Get a list of CLUEs:<p><pre><code>   grep -C 3 CLUE crimescene
</code></pre>
Get a list of the 3 possible suspects based on CLUEs:<p><pre><code>   grep -f &lt;(grep -f memberships&#x2F;AAA  memberships&#x2F;Delta_SkyMiles | grep -f memberships&#x2F;Terminal_City_Library  | grep -f memberships&#x2F;Museum_of_Bash_History) -C 3 vehicles  | grep -A 6 L337..9 | grep -B 1 -A 4 Honda 
</code></pre>
Then read their interviews:<p><pre><code>   grep &lt;Owner&gt; people 
   tail -n +&lt;line&gt; streets&#x2F;&lt;street&gt; | head -n 1
   less interviews&#x2F;interview-&lt;interview number&gt;
</code></pre>
Take your guess :)
