Herb Gaffer.

Retired CONTROL agent and keen amateur ornithologist living at Spy City retirement home.

In the words of Maxwell Smart, Herbert "Herb" Gaffer is "the world-famous CONTROL Agent No. 4," Max's idol after whom he has patterned his technique and style.

When Max is sent to Spy City for Gaffer's diary—in which he has recorded all of CONTROL's secret codes and procedures—Gaffer is kidnapped from his room by KAOS right under Max's nose and tortured for the location of the diary.

Gaffer withstands the treatment without cracking and Max and 99 are able to rescue him before the diary falls into evil hands.
