Maigret is visited by a troubled man and asks him to keep
in touch, hoping to curtail his criminal impulses--but when
the man disappears, Maigret must investigate a crime that
may or may not have occurred
When Maigret returns home at the end of a long day, he is
surprised to find a tense man named Léonard Planchon waiting
on his doorstep with an unusual problem. Planchon wants to
kill his wife, or perhaps his wife and her lover, who for
two years have been making him sleep on a cot in the dining
room. He has even worked out a plan to hide their bodies in
concrete. Uneasy and hoping to stop the man before he goes
too far, Maigret must investigate a murder that has not yet
been committed and uncover the truth behind this peculiar
ménage à trois.
A fast-paced, psychologically astute mystery, Maigret and
the Saturday Caller follows the inspector through
Montmartre as he patiently questions Parisian partiers,
bartenders, and others as to Planchon's whereabouts,
stripping away a bit more of the mystery's camouflage with
each encounter until they lead him to their shocking conclusion.
