Lestrade headcanon from Rupert Graves

Anne Cunningham from The US asks: I am sure you have your own back story and personality traits that you have put together to bring to life Lestrade. What can you tell us about your Lestrade that we wouldn’t learn in any of the episodes ?

Rupert Graves: I don’t really like to tell secrets, I really don’t …. one thing, but ONLY one … he’s a secret gambler.
