Guillaume de l'Aubespine de Châteauneuf

[4] In February 1586, Châteauneuf complained to Francis Walsingham that his lodgings were small and had a bad smell, and made his daughter unwell.

He hoped that Walsingham would move him to an empty house belonging to Mary Sidney, Countess of Pembroke.

[5] Walsingham had kept spies in Castelnau's household and now determined to intercept Mary's correspondence arriving at the French embassy.

[7] Châteauneuf later described how Gifford would carry secret letters from London to Mary at Chartley Castle.

She suggested writing sometimes on supplies of white taffeta or fine linen using invisible ink made with alum.

[12] Anthony Babington was captured in London and the event became a celebration with bonfires and the ringing of church bells.

[13] In September 1586, Châteauneuf wrote to Courcelles, a French diplomat in Scotland, describing the arrest of Mary's secretaries Claude Nau and Gilbert Curle.

Daniel Dumonstier made a drawing of Marie de La Châtre, and at least two other portraits survive.
