On 14 June 2017, a fire broke out in the 24-storey Grenfell Tower block of flats in West London; it caused 72 deaths and more than 70 others were injured and 223 people escaped. On the fourteenth floor of Grenfell Tower, firefighters moved eight residents into one flat – 113. Only four would survive. Piecing together evidence from phase one of the Grenfell Tower Public Inquiry, Katie Razzell tries to understand what went wrong that night in flat 113.
