Good point regarding Banks casting, especially when you consider Nick got a bit hot under the collar about Caroline Morris playing Erimem.
I agree it was quite unbelievable even at the time. And if I recall correctly (and it's very possible I don't) Briggs made those comments about Morris around then; it was also when Sophie Aldred was cast as Chinese girl Lila in The Avengers (Brought to Book released in January 2014) which also stood out as a extraordinary decision.
It wouldn't have been an issue if Erimem had been a white Eqyptian, who, according to experts, where around in the time of the Pharaohs. However its pretty clear in the stories she is a POC. As for the Aldred casting, yes it was pretty ridiculous considering the amount of young Asian actors available.
There is a gap at the top end of my Monthly Adventures collection just waiting to be filled by A Life of Crime, Fiesta of the Damned and Maker of Demons, so they are all definites. Just have to see if I can scrape together enough pennies for the New Adventures Vol 1 before Sunday..
