Mr McPherson had claimed to be asleep when Paula died and said that her 13 injuries, including grazes and bruises, must have been caused by his attempt to drag her body from the pool.
Paula’s family, however, insisted that she hated swimming and didn’t even intend to buy a swimming costume for the trip that her husband had solely planned.
They claim that Paula had always preferred city breaks and would never have chosen the remote cottage as a holiday destination.
Before unlawfully killing Paula, McPherson both dishonestly forged trust documents to secure control over money payable on Paula’s death and forged a signature of a supposed witness of her Will.
Hours after his wife’s death, McPherson transferred more than £20,000 from their joint account to satisfy his debts and ate a steak dinner.
Mr Richard Justice Smith stated that the “critical question” was how Paula ended up in the water, which was only 4 feet deep, unable to save herself.
He ruled that she must have been unconscious and that the distribution of her neck injuries suggested compression from an arm lock by her husband.
