agreed. My son has rung me at 3 in the morning before and I'm literally awake in seconds panicking.
I, too, have had calls between 1 and 3 in the morning. I've known, instinctively, that something was wrong and acted accordingly. Which is one reason why I don't believe the phone call happened. If Nevill HAD called Jeremy, he'd have been panicked. Indeed, Jeremy, eventually said he had. But Jeremy failed to respond like someone reacting to a "panicked" phone call.
