Kitsune - I assumed that the first three letters were a truncated version of a word that loosely means "wild". The last three letters are in Chambers.
For myself I'm frustrated by the endgame and a bit fed up of grid-staring. So far I have two unorthodox versions of familiar surnames and a third who was the focus of their collaboration. I can guess at a (short) cryptic representation of a relevant quote.
If they are the trio then I have one name for the duo who made a similar statement. According to Google the person they were speaking to does not appear in the grid - a significant letter is entirely absent from the grid - and I have no idea how that quotation might be depicted.
Am I miles off?
