Even now, days after Peter Murrell pleaded guilty to embezzling £400,000 from the SNP where he was chief executive, I am still staggered by his estranged wife Nicola Sturgeon's claim that she was ignorant of his crimes.
The evidence was there in front of her nose: a £124,550 motorhome, a £3,232 coffee machine, a £3,500 silver wine coaster.
She can't have the foggiest idea what anything costs. If she did, she'd have realised that on Murrell's salary – believed to have been around £100,000 – he didn't have this kind of spare change.
And yet perhaps it shouldn't be so surprising. We all know of wives who haven't a clue about their husbands' misdemeanours – and vice versa.
Critics of Sturgeon blame her lack of curiosity.
