In this, Lines of Enquiry’s inaugural ‘Case Notes’, John Sweetman introduces a new strand of his hit true crime podcast series. Stepping away from any one specific case in detail and instead revisiting past investigations and responding to listener questions, John takes us behind the scenes of Lines of Enquiry.

This first episode of ‘Case Notes' is also the last in Season 1 of Lines of Enquiry. Reflecting on his first season, John is in conversation with Darren Cleary, creator of Lines of Enquiry and Head of Digital Audio at Bauer Media, who hears all about Season 2, which goes out on January 6th, 2026, with further 'Case Notes' also on the way.

When Anne O'Sullivan was diagnosed with terminal cancer, tensions within her family about who would inherit her substantial plot of farm land came to the surface.

Soon, Anne would find herself awake before dawn, running through fields and ditches to a neighbour's house to get help as a terrible darkness descended on the family farm.

This is a tragic story that saw a family torn apart as their home became consumed by fear and threats of violence towards Anne and her eldest son, Mark. Those rising tensions would lead to the most unfathomable and shocking moment of hatred and rage.

In this episode of Lines of Enquiry, John tracks the descent into violence and revisits his case notes on the letters that proved crucial to any understanding of events of that tragic day.

On St Patrick’s weekend 2024, 23-year-old Kelly Lynch travelled from her home in Armagh to Monaghan to support her boyfriend after a sudden death in his family. Two nights later, on the walk home from the pub in the town, on the Friday night of a busy bank holiday, Kelly disappeared.

She was found in the Ulster Canal on the Sunday morning. Gardaí said Kelly had drowned and quickly confirmed they were not treating her death as suspicious. But as the details emerged, her family were left with devastating questions.

In this episode of Lines of Enquiry, John Sweetman follows Kelly’s final movements, the contradictions at the heart of the investigation, and the campaign led by a family desperate for answers.
