I did a Google Image search for the original source of this photo (From Doctor Who Magazine‘s Twitter, actually) and it suggested it was a picture of a “gentleman.” I find that appropriate.
But we lost Terrance Dicks today. He wrote several Who serials, script-edited many more, helped devise the third and fourth Doctors, and penned several dozen novelizations of Who stories. It’s no exaggeration to say that when I was thirteen, I didn’t want to read anything else. Our condolences to Terrance’s friends and family.
