Netflix’s ‘terrifying’ new true crime doc produced by Louis Theroux rockets to number one

'Watch it during the day time with all the lights on,' one viewer warned.

The two-part doc is titled Can I Tell You a Secret? and tells the story of some of the women targeted by serial stalker Matthew Hardy.

In 2022, Hardy received the longest custodial sentence in British history for stalking online, with the series exploring "the women’s experiences, the police investigation and how Hardy was ultimately brought to justice".
