There was more intense viewing on Sunday night as Trigger Point aired.
We're now more than halfway through ITV's brand new drama and many viewers are now firmly on the edge of their seats.
Following the murder of a Counter-Terrorism officer during last weekend's episode, Lana Washington and the EXPO team were once again in a race against time to stop the bombers before they strike again.
The end of week three's episode saw Lana checking the lockers of her fellow Bomb Disposal Squad members, only to find an A-Z of London books of maps with post-it notes and markings to suggest plans for the attacks that had already taken place - and potentially more to come.

Early in Sunday night's episode, we saw her pass on the information she has to DCI Thom Yungblood who is working on the case, as well as being her boyfriend.
Meanwhile, Lana was struggling to get hold of her brother Billy who she had to rescue from the police station for smashing the window of an Halal butchers.
She later confronted her colleague, John, asking what he had got her brother into, thinking he was grooming her younger sibling.
But things soon took a turn when Lana got a call from her bosses telling her they believed Billy was a member of the terrorist group after being caught with a recently killed member of the same group.
They roped Lana into calling her brother and when he finally answered with the ploy his sister was with his ex-girlfriend.
And Billy soon discovered he had been set up and he wasn't picking up his mates at all and that his car was rigged with a bomb outside a tube station in the middle of a protest.
He was soon directed to a playing field where the police and bomb squad were waiting.
Lana soon arrived at the scene, after being instructed to take personal leave after her outburst at colleague John, and tried to calm her brother down as she figured out what was going on.
As a timer on a device ticked down, Billy panicked and tried getting out the car, while Lana believed the timer was just a scare tactic.
But as Billy opened the door, the car exploded and went up in flames with Lana's brother inside.
Despite the shocking scenes, Trigger Point viewers were distracted as they discovered Billy had a famous lookalike.
