I mentioned earlier that there were still seven "Cadfael" novels that were not translated for the small screen; seven opportunities for us to see Sir Derek Jacobi play the role again.
These are the novels by the late Ellis Peters which could be adapted:
Dead Man's Ransom (1984)
An Excellent Mystery (1985)
The Hermit of Eyton Forest (1987)
The Confession of Brother Haluin (1988)
The Heretic's Apprentice (1989)
The Summer of the Danes (1991)
Brother Cadfael's Penance (1994)
Here's hoping someone takes up the call for Jacobi to take up the cowl once more.
