plumb the depths, to

Get to the bottom of something. This term has been used literally since the first half of the 1500s for measuring the depth of a body of water, using a line weighted with a lead ball, or plumb. Its figurative use came a few decades later and has survived the death of the literal meaning, which gave way to more sophisticated means of measuring. E. W. Gregory used it in The Furniture Collector (1916): “. . . engaged in trying to plumb the depths of duplicity to which dealers can descend in faking old furniture.”
