Milverton blackmails Mary, exploiting her dalliance in antigovernment activities as a student. Sherlock decides to sneak into Milverton's estate to steal his evidence, but even that act was anticipated. Sherlock finds that he is not the only trespasser.
Before he returns,
I will sneak into his mansion
Ich schleiche mich in sein Anwesen,

Je vais profiter de son absence du manoir
Antes de seu retorno,
entrarei em sua mansão
Я проникну туда, пока его нет,
