A lady and gentleman are making love to one another in the drawing room
of a flat in Ashley Gardens in the Victoria district of London. The lady
is a young widow, Grace Tranfield, in love with the man, Leonard
Charteris, who is the 'philanderer' of the title. Grace is shocked and
disconcerted to find that Charteris, on his own light‐hearted admission,
has been in a similar position with Julia Craven and others. The affair
with Julia, in fact, has never been broken off. He maintains that it is
not his fault that half the women he speaks to fall in love with him;
and he is in full flight of cajolery when Julia Craven herself erupts on
to the scene, attacks Grace, and announces her intention of staying
until Charteris has given her up.
