A FILM of Neil Gunn's book The Silver Darlings was made as far back as 1947 and is often viewed by audiences at different events in Caithness ("Neil Gunn and the Silver screen test", The Herald, December 5).

It is readily available on DVD from that well-known online distributor named after a large area of northern Brazil.
