When DI Mooney is calling Anna, her hone number starts +448. +44 is the international dialling code for the UK, but all mobile phone numbers start with a 7. Or 07 when dialled from within the UK.
Also, mobile numbers have a total of 10 numbers. The telephone number displayed on screen only had 9, plus the country dialling number.
The bottle of wine that DI Mooney opened to drink with his dead wife's photo was a Sauvignon Blanc but the label said it was 250ml, when the bottle was clearly a 750ml size.
