A best-selling German author was found murdered on her houseboat as police search for the suspect responsible for her death. 

Police in Hamburg said a 58-year-old woman, who was later identified by the Guardian as Alexandra Fröhlich, a bestselling novelist, was found lifeless by her relatives on her houseboat on Tuesday morning.

One of Fröhlich’s three sons found her body, according to police. Authorities believe she died between midnight and 5.30 a.m.

After investigators looked over the evidence, authorities said they now believe that Fröhlich died “as a result of violence.”

“The journalist and author Alexandra Fröhlich has literally achieved a West-East satire to shout with her novel ‘My Russian Mother-in-Law and Other Disasters.’ The novel is a fun read not only for Russia insiders that strengthens the laughing muscles on dreary winter days,” one review read. 

Fox News Digital reached out to Hamburg Police, but did not immediately receive a response.
