Well well well.
This link (posted by someone upthread, many thanks but I can't recall who) https://ericrasmusen.substack.com/p/who-hired-the-ridiculous-jason-arday gives the panel who appointed Arday.
I am very familiar with the work of one of them, one of whose books had a large overlap with the field of my own PhD. It was so inaccurate that it actively confused me. Names are misspelt, quotes are cherry picked (and in at least one case, edited to fit the narrative), timelines are sometimes confused, the referencing is poor (incorrect page numbers and dates, for example), and some of the information is just wrong (including some that is very significant). All the significant errors of fact - rather than those produced by patchy general knowledge - tend in the same direction.
The incident that particularly got me was the reliance by this person on a biased source written some months after events in preference to the contemporary diary (which he cites) of the man at the core of the incident. This allows the author to press on with a persistent lambasting of the British Empire as uniquely dreadful.
I'm no fan of imperialism, but there is plenty to criticise about the BE without, as this person does, making stuff up. I concluded long ago that the book I'd read was likely to have a pernicious impact on both faith in democracy and our view of British history.
I have a whopping great document detailing it all on my laptop...
