Impertinent neighbour spreads rumours about me and I cannot defend myself because I am abroad !



Impudent neighbour spreads rumours about me and I cannot defend myself because I am abroad ! About a reliable person I have learned that my neighbour claims I am in prison ! Allegedly I have maltreated a domestic help.
In fact, a police investigation or procedure is underway. But with reversed signs ! Not I am the accused, but the foreign domestic helper is accused of various offences. I do not want to go into detail on this, as the investigations are still ongoing. Anyway, the lady is back in her home country.
The neighbour who spreads the rumours is jealous of me. My house is paid for, she has a mortgage. My garden is lovely, her garden... well...
I live in another European country and cannot go back for health reasons and because of the quarantine measures.


So I cannot confront her either!


Should I have a lawyer send her a warning letter?


However, I do not want to involve the person who sent it to me.
