The flat was where Suki lived until Nish got out of prison to play happy families again.
(Currently, where Ravi and Nugget live).
Memory stick film shows Suki fighting off and 'killing' Ranveer (old family friend but her business rival), who attempted rape and strangulation after Suki reneged on a fake promise to have sex with him in exchange for a business deal.
Suki had set up the covert filming for blackmailing purposes re his threats.
She clonked him over the head with a clock. Thought she'd killed him. Ravi walked in, saw what looked like his dead father *(see note below).
Sent Suki out so he could deal with the body.
However, Ranveer was still alive. Ravi used same clock to finish him off. Suki still believes she murdered him...
Ravi cut up Ranveer and shoved body parts in suitcase (yes, really).
He hid it in some woods. Grim.
The remains were later discovered by dog-walker (isn't it always a dog-walker?).
Kheerat (Nish & Suki's eldest son) blamed Ravi, Ravi blamed Suki. Kheerat agreed to take the rap to protect his mother.
*Ravi was Ranveer's adopted son (later revealed to be biological son of Nish, who had had an affair with Ranveer's first wife.
Yes, the same Nish, who constantly witters on about 'family values'. Bloody hypocritical bugger).
Ravi was having an affair with Dr Nina, Ranveer's younger, glamorous second wife. i.e. his step-mother. Keeping in the family, this lot!
They were planning to run off with Ranveer's fortune, until she heard Ravi had murdered his Dad.
So, the memory stick footage has been edited (presumably by Ravi?). Making it appear that Suki did indeed murder Ranveer.
