Castle where Bothwell was also held. Randolph wrote to Arran's old ally Throckmorton that the Earls had fallen into a "cesspit of their own making." The Duke was forced to resign the keeping of Dumbarton Castle. Arran's expenses at Edinburgh Castle, where he was kept by the Earl of Mar, were paid by Mary, Queen of Scots, from her income known as the "Thirds of Benefices". The cost was 40 shillings daily amounting to £732 Scots for a year. An account of his household expenses was kept by two of Mar's servants, the chaplain Andrew Hagy and Jerome Bowie. Randolph described Arran in a letter to Cecil in January 1564, saying he inclined to solitariness, in dark rooms, with little company or talk, and was suspicious of all he met. He was also troubled with jaundice. He ate little, and spent most of his time in bed, without getting sound sleep. His father came to Edinburgh in January 1565 to ask Mary for his release. She visited Arran in the castle and kissed him, but he spoke few words as an apology to ask for forgiveness, and remained a prisoner. Arran was released in April 1566 and went to Hamilton, sick and without the power of speech. He was to remain within four miles of Hamilton Castle. His father died at Hamilton on 22 January 1575. He inherited his father's estate, but because of his insanity, he was placed under the care of his brother John. John and his other brother Claude, Abbot of Paisley kept Arran prisoner at Craignethan Castle, and though Henry Killigrew reported in August 1575 that if he were well-used and at liberty there was hope of recovery, he was never again allowed any freedom. His mother, Margaret Douglas, and aunts Elizabeth Douglas (the wife of Regent Morton) and Janet or Beatrix Douglas wife of Lord Maxwell, his sister Anne (mother of the Earl of Huntly), and youngest brother David were all also affected by mental ill-health. Thomas Randolph wrote that Arran "has twice before been in the same case," and his mother and aunts were "certain times or the most part of the year distempered with an unquiet humour." Randolph's description of Arran's symptoms sound akin to modern diagnoses of mania and bipolar disorder although details of his psychological condition will remain unknown. John and Claud were supporters of Mary Queen of Scots, and so
