It is exactly 15 years since MI6 spy Gareth Williams tragically died at the age of just 31.
On August 16 2010, in one of the most mysterious and bewildering deaths ever on British soil, police said he impossibly folded himself inside a red North Face holdall in his bath.
His Pimlico bathroom was spotless and officers found no evidence of Gareth's fingerprints on the padlock of the bag or even the rim of the bath that the bag was found in.
Detectives found no signs of struggle and no bruises or marks on his body. The heating was on full blast - despite being the height of summer - the bathroom door was shut, the shower screen closed and the lights were switched off.
The Welsh prodigy, considered a puzzle-solving genius, had been scooped up by GCHQ having completed his GCSEs in primary school, A-levels at 13 and his maths degree at 17. But the solution to the puzzle surrounding his own death, remains unsolved.
