Fraulein Schmidt and Mr Anstruther

What on earth could have induced Mr Anstruther to fall in love with Fraulein Schmidt? He is an eligible English bachelor from a good family with great expectations; she is the plain, poor, 'spinster' daughter of a German scholar. But Rose-Marie Schmidt is also funny, intelligent, brave and gifted with an irrepressible talent for happiness. The real question is, does Mr Anstruther know how lucky he is?
