In "The Markenmore Mystery" (1922) by J. S. Fletcher, Harry was talking with his neighbour about his ill old father and the possibility of his death at anytime:
“Well, I must go,” the neighbour said. “You’ll be sure to let me know if there’s anything I can do? But you say Sir Anthony’s not in immediate danger?”
“Not immediate,” replied Harry. “But—any time. And, as he’s fidgety about not being left, you’ll excuse me if I go back to him? If he seems a bit stronger tomorrow, I’ll tell him you’re home again, and no doubt you can see him when you look in. You’ll come again soon?”
Shouldn't it have been "fidgety about being left" to show that he gets nervous when he has been left alone?
