Pick of the Day

The Case I Can't Forget, 9.35pm, RTÉ One

Here's more from the series in which some of Ireland’s top detectives describe, clue by clue, the stand out case that has shaped their career.

In this week’s episode, retired Sergeant Major PJ Higgins of the Defence Forces takes viewers back to the chaotic search in 1983 for kidnapped Quinnsworth executive Don Tidey.

Snatched from near his home by the IRA, it took the combined efforts of An Garda Siochana and the Defence Forces three weeks to track Tidey to dense woodland in county Leitrim.

It’s a rare positive representation of Traveller culture on national TV, so well worth a look.
