The Nichols Library gives a tip of the hat to author Robert B. Parker, creator of the Sepenser detective series, who passed away last week.    Spenser, his signature character, was a wise-guy P.I.,  who quipped and cooked his away some 37 stories between 1973 and the present.   Readers seldom read just one.  See our article in this week’s Meredith to find out more about Spenser and Parker’s other fiction.
