About This Episode
In 1975, British police launched one of the most ambitious drug investigations ever undertaken, targeting two LSD manufacturing operations run from rural Wales and London. Over the next two and a half years, more than 800 officers from 11 different police forces would work to dismantle what amounted to one of the world's largest acid production networks.
The investigation began with officers working undercover at major pop festivals including Reading and Windsor, observing drug trafficking patterns. A fatal car accident in the Welsh village of Machynlleth provided additional momentum for the inquiry. These early leads would eventually unravel a sprawling criminal enterprise that reached across continents.
At the centre of the Welsh operation stood Richard Kemp, a chemist living at Penlleiniau cottage near Tregaron. Kemp was no newcomer to drug manufacturing—he had been producing LSD since the late 1960s. His operation involved associates including David Solomon, linked to Plas Llysyn, and Alston Frederick Hughes, known as "Smiles." Dr. Christine Bott, Kemp's girlfriend and a general practitioner, was also implicated in the ring.
In London, Henry Todd led a separate manufacturing operation. Todd had recruited both a tabletter and a chemist, drawing inspiration from the Timothy Leary scene that had flourished at Cambridge University. Andy Munro served as the chemist for this ring, operating from 23 Seymour Road in Hampton Wick, Kingston Upon Thames. Leaf Fielding worked as a tabletter for the London operation, based in Binfield Heath. Brian Cuthbertson rounded out the London ring's key players.
