Almqvist's younger half-brother was Director-General Gustavus Fridolf Almquist (1814–1886),[5][6] who was the father of Agnes Hammarskjöld.
In 1823 he gave up his post, and in the autumn of the following year moved to Adolfsfors-Köla in northern Värmland where he and some friends, inspired by Jean-Jacques Rousseau, intended to live out a rural idyll.
[8] In June 1851 Almqvist fled Sweden on suspicion of fraud and poisoning attempts against an elderly usurer named Johan Jacob von Scheven, to whom he owed 18000 riksdaler.
Some dealt with his radical views on society and politics; in his novel Drottningens juvelsmycke, his main character, Tintomara, is neither male nor female, and arouses both men and women to fall in love, and in his novel Det går an, a woman lives with a man without being married to him.
Sara Videbeck and the Chapel is the English translation of Almqvist's most famous work, whose Swedish title is Det går an.
In it, sergeant Albert falls in love with Sara Videbeck, a glazier's daughter, during a steamboat trip between Stockholm and Lidköping.
