Henry Panhacker is a character in the stage plays Fiddlers Five and Fiddlers Three. He is the son of the business tycoon Jonathan Panhacker. Stage directions describe Henry as "a nervous young man with an occasional stammer, he wears big horn-rimmed glasses making him look rather owlish." Henry is a partner of Sam Fletcher in a venture that is in jeopardy because of lack of money. The only hope is a sum of one hundred thousand pounds which Henry expects to receive from his father, that is provided his father lives for another week and wins a wager.
Henry tells the others that he has always been a disappointment to his father as he is too ordinary and cautious while his father is a gambler and risk-taker. His father laments that Henry is more interested in birds and nature than in business. The whole purchase of making over the winnings of the wager to Henry is to teach him a lesson that it is worth taking risks.
When Jonathan dies too early, some "fiddling" becomes necessary. At least in the Fiddlers Three version, Henry is not considered a fiddler--there are only three of them. To the others, Henry is a liability because they think he is too straight to hold down a lie. Sally Blunt, for example, has to send him away to prevent him from meeting Dr Nolan because he might contradict her in her account of who the dead person is. It is possible that Henry's character has been "toned down" from the Fiddlers Five version where there are five "fiddlers".
