David and Tracy are outbid as they try to buy No.8 in Corrie

But who is the mystery bidder?

Having failed to secure a mortgage, David and Shona are at their wit’s end. When Shona asks Audrey if she can lend them the money to buy No.8, Audrey reminds her that David stole from her. And when Steve returns from the Peak District, he's shocked to find out that Tracy intends to buy No.8.

Spotting a telecommunications engineer crouching in front of an open cabinet with all the wires hanging out, Shona has an idea and disconnects all the wifi so that she can stop Tracy from buying the house.

As Tracy and David head out onto the street, both furious that the wifi is down, Shona announces that it’s her doing. As she tries to explain her actions, David and Tracy start a frenzied bidding war.

When the bidding reaches £138k, Steve forbids Tracy from going any further causing her to angrily slam the lid shut on her laptop.

However, Tracy and David are equally shocked to discover that the final bid of £138k was placed by an unknown party. Spotting a light on in No.8, David and Shona knock on the door, desperate to find out who the mystery bidder was.

Corrie continues Mondays, Wednesdays and Fridays at 7.30pm and 8.30pm on ITV
