Ah, yes, I see that I have.
Richard says of Collected Works:
Though Nick Wallace is named as the editor of this anthology, I suspect that a great deal of credit is also due to Philip Purser-Hallard. He has written five linking interludes, entitled “Perspectives”, which focus upon the Quire - a clan of fascinatingly strange visitors from humanity’s distant future, who crop up throughout this carefully controlled book - and he also co-wrote the final tale, “Future Relations”, with Wallace.I'm not sure that that's entirely fair to Nick, but it's still pleasing to hear.
