"Who is Conrad Hirst?" was received well and was short-listed for both the prestigious Edgar Award and the Barry Award (both in the USA). Once again, this book was not published in the UK, but it's now available there as a Kindle e-book and has also been published in Finland, Germany (as "Die Letzte Wahrheit"), Japan and Poland. It continues to attract new fans, and was No.1 in the Australian Kindle chart as recently as 2018, a full eleven years after first publication.
