HISTORY NOTES

'Titus Discovers', the third play in my The History of Titus Groan, based on the novels of Mervyn Peake, will be broadcast, on Radio 4, tomorrow, Sunday 24 July, at 15:00.

And if you missed the second part, 'Titus Inherits', you can catch it again tonight on Radio 4 at 21:00.

And two hours later (if you're still awake!) you can hear. a repeat of the panel game Quote... Unquote... again on Radio 4 at 23:00.

Nigel Rees is in the chair and my fellow contestants are Shelagh Fogarty, Ardel O'Hanlon and Martin Jarvis, but no prizes for guessing which of us quoted American New Yorker humorist, Robert Benchley, who, on visiting Venice for the first time, cabled home: STREETS FLOODED. PLEASE ADVISE!
