The death was announced earlier this week of Rose Dugdale, the English aristocrat who became a member of the IRA, served time in prison and was subsequently involved in perfecting bomb technology for the Provos.
She also featured in attempts to rid inner city Dublin of drug dealers in the 1980s.
Seán O’Driscoll has written a biography of Ms Dugdale, entitled Heiress Rebel Vigliante Bomber. Seán is this week’s guest on the podcast.
