Just looked at this and can't work this out.
In Google I can't find Mandaites. In Chambers only Mendaites, but still don't understand the word play.
Kaya, would appreciate your insight.
Thanks
It was not a typo as I posted what I had in my grid. My mistake was, after finding the word in Chambers, to enter it incorrectly.
Thanks to slaney and ros for the correction.
