I thought that this might be of interest to you all.
I'm the Co-Administrator of a literary/book review site and I've recently interviewed Jay Benedict, who played John Kieffer in the Foyle's War episodes "Invasion" and "All Clear".
Quite apart from being a lively and wide-ranging interview (the first he's ever given, I believe ...) he mentions Mr Horowitz - not once, but twice.
Firstly, as one of his children's favourite authors, and secondly in a rather sweet 'thank you' for creating the role of Kieffer and writing it so well!
I should, perhaps, just mention that for anyone who hasn't yet seen "All Clear", the interview contains a major spoiler.
I ought also to mention that Jay has a colourful turn of phrase from time to time ...
He was very surprised to be asked, I think, and if anyone would like to leave a comment - or just say 'hello', it would be nice. (The interview has been read by hundreds of people, but very few have left comments ...).
You can do so without being a registered member of the site. All you need to do is give a name and your email address - which will be visible only to the site Administrators.
I hope you enjoy the interview. http://vulpeslibris.wordpress.com/2008/07/17/france-week-in-conversation-with-jay-benedict/
