I'm just a walking mass of useless information.
Actually it was a bit of classic detective novel deduction:
There certainly couldn't be many stories with a character named Bundle, so that rang a bell. Lady Eileen Brent (Bundle) was an Agatha Christie character in only two of her novels: The Secret of Chimney, and The Seven Dials Mystery. In the upper right corner the name Jimmy Thesiger can be seen (at least enough of it); he only appeared in The Seven Dials Mystery, as I recall. It took a fair bit of thinking, and a trip to Wikipedia to check my memory but, yeah.
Elementary, my dear @blueskies_!
