The Captain is the ghost of a World War II army captain who resides in Button House. He is portrayed by Ben Willbond. Most of his personal life remains unknown, and even his given name was not revealed until near the end of the series. As a ghost, he seems to be closest with Fanny and Kitty.
He was born in Bledlow, 1900, likely sometime in November, as he turned 18 roughly around the armistice in WW1, as he reached the front lines just as the ceasefire was announced. During WW2, The Captain was for the most part stationed at Button House. He was C.O of a unit charged with HQ duties with his second-in-command being Lieutenant Havers, until he was transferred. It is unknown precisely what The Captain was charged with achieving although it can be speculated that it was research into new weaponry, as he alleges that he was the only one aware of a top-secret project called Operation William. William was a secret prototype limpet mine which The Captain buried in one of the gardens (though why is unknown) shortly after Havers left for North Africa. If Cap really was in charge of armaments research, it would explain his particular fondness for weaponry.
