The Mirror: 'Brilliantly tense' unveiling scene in a finale which 'neatly tied up' loose ends

The Daily Mirror's Sara Wallis described the scene in which 15 million viewers discovered the identity of 'H' as 'brilliantly tense'.

But Wallis said creator Jed Mercurio would be unlikely to give everything away adding: 'Where would be the fun in that?'
