Tom Vernon RIIP: Fatman vs Batman

On perusing back through the Deaths in 2013 site, I noted the following addition to September 11th:

Tom Vernon, 74, British writer and broadcaster ("Fat Man" series), heart attack.

Note the following from his wiki page:

 Tom Vernon (23 April 1939 – 11 September 2013)^[1] was a British broadcaster and writer, best known as the titular "Fat Man" of a number of popular travelogues.

That the name Tom means twin in origin is a heads up... the first clue that his inner twin influenced their "timely" deaths.  Note the following info regarding his birth date:

 April 23 -  is the 113th day of the year (114th in leap years) in the Gregorian calendar. There are 252 days remaining until the end of the year.

This date falls into the recent "Off By Two" pattern-cluster... as in two off from the 111st day of the year.  Note the following regarding his day of death re en.wikipedia.org/wiki/September_11

September 11 is the 254th day of the year (255th in leap years) in the Gregorian calendar. There are 111 days remaining until the end of the year. 

On 9/11, the day that Tom Vernon passed away, there are 111 days remaining in the year.

Note as well, the above excerpt from his wiki page, that says he was best known as the titular "Fatman" hence falling into the "Fatman/Atomic Bomb" pattern-cluster.  Just key in Fatman into the search box at the top of this page and many related posts will be brought up.  It's also interesting to note that my September 12 post re: Keith Dunstan RIIP: Brownstone, Brick and Masons, reveals that 

Newspaper columnist Keith Dunstan who also passed away on September 11 and listed on the Deaths in 2012 site, had referred to himself as Batman.  Audd that on the same day two notable persons would pass away, one referring to himself as Batman and the other Fatman?!
