This is a sweet little graphic novel by the whimsical writer/illustrator Jean-Jacques Sempe. It follows the day-to-day presence and absence of the titular Monsieur Lambert from his local bistro, which the remaining regulars take as an opportunity to gossip regarding his whereabouts. Lambert, unlike the stuffy locals who populate the bistro everyday, is a romantic figure whose absence prompts the bistro denizens to recall their past lovers and exploits. In classic French fashion, the novel ends without the bistro clients ever really knowing where or what Lambert is up to during his absences. He reappears as mysteriously as he left, only to disappear again. The illustrations, as with everything that Sempe draws in The New Yorker and elsewhere are whimsical representations of the lively figures and locales they depict. Delightful.
