The main emphasis here is hardly on gloom. It is on the prodigious research and love of trivia that inform Mr. Brown’s stories, the ease with which he sets them in motion, the nifty tricks (Dante’s plaster death mask is pilfered from its museum setting, then toted through the secret passageways of Florence in a Ziploc bag), and the cliffhangers.
