How did you stumble on this ancient monolith?

In his book City Adrift (2013), Naresh Fernandes unearthed British archaeologist KRU Todd's tryst with microliths in Bombay. Intrigued, I dug further, a search that led me to three publications by Todd between 1932 and 1950 — all focused in his exploration of prehistoric man in Bombay. Three of his original publications will be on tactile display at the talk. As always, 'Please Touch' is my motto with archival material.
