Your wife left you a message... the English one.
They may not be the exact words, but pretty close. Maybe I'm just looking too much into it, but why did the receptionist at the hotel add on 'the English one.' The receptionist would have no reason not to believe Fields wasn't his wife, so why the extra fact for clarification?
Or, is it because Bond is walking into the hotel with Camille, and the receptionist thinks it's his 'other' wife, on the side? If so, you wouldn't really assume and say something like that to the guest...
It's such a small thing, but I picked up on it on my 4th viewing.
