Aaron and Robert step up their hunt for the arsonist as tensions rise in Emmerdale

Could the culprit be closer than they think?

 16-22 MAY

Putting out a second fire on the farm, this time closer to a feed store, Robert and Aaron speculate on who’s starting them and the hunt for the arsonist continues.

Lydia still holds a grudge against Sam for missing her dance class, and feeling inadequate, Sam wants a secret word with Ross.

When Kammy turns up late for work, Aaron lambasts him and urges him to pull his weight, noting that Kammy looks tired and has his shirt on backwards.

Meanwhile, in a barn on Emmerdale Farm, Sam and Ross analyse the space, deciding it’s exactly what they’ll need. But Ross thinks they’ll need a cover story for why they’re up there, before giving Sam a lighter and asking him to do the honours.

As Aaron and Robert approach the barn, Sam makes a run for it, undetected and they question Ross about what he’s doing, and he tells them he was looking for the arsonist, posing the idea of paying him to keep investigating, which Robert considers.

Later, as Ross explains his plan to Sam, Nicola watches in disgust as they spit and shake to their scheme. But after another fire, Robert suspects they’re being targeted and is left fearful when Ross floats the idea that Kev is behind the fires.

Soon, Aaron calls attention to how little they know about Kammy, and Robert agrees to triple Ross’ pay to find the arsonist, but Aaron suspects Ross may well be the arsonist.

Later, Aaron and Robert follow Ross and Sam, convinced they’re the fire starters.

As they vow to find the arsonist, neither sees Kammy listening in, looking alarmed.

Emmerdale continues Monday to Friday at 8pm on ITV1 with first look episodes available from 7am on ITVX
