She left the inn. What was she going to do now? She had no idea where Rollo might be. There was now little point in denouncing him to Ned, for Ned would not be able to find him either. She racked her brains. People were going to commit an atrocity, and she had to stop them.
 
 Could she give warning? Perhaps she could do that without condemning Rollo to death. She considered an anonymous letter. She could write to Ned, disguising her handwriting, and pretend to be one of the conspirators. She need not say anything about Rollo. The letter would simply warn Ned to stay away from the opening of Parliament if he wanted to live.
 
 But that was implausible. Why would a Catholic conspirator want to save the life of a famous Protestant courtier?
 
 On the other hand, if the letter went to a Catholic, he might approve of the plot and keep the news to himself.
 
 What she needed was someone in between: a man who was loyal to the king, but sufficiently friendly to Catholics that they would not want to kill him. There were several such people at court, and Margery thought of Lord Monteagle, a Catholic who wanted to be at peace with his Protestant countrymen. People such as Rollo and Bartlet spoke of him as a weak ditherer, but Margery thought he was sensible. If he were warned he would sound the alarm.
 
 She decided to write him a letter.
 
 She stepped out to one of the many stationery shops in St Paul’s Churchyard and bought some paper of a type she did not normally use. Back in the house, she sharpened a quill with a pen knife. Using her left hand to disguise her writing, she began:
 
 My Lord, out of the love I bear to some of your friends, I have a care of your preservation.
 
 That was nicely vague, she thought.
 
 Therefore, I would advise you as you tender your life to devise some excuse to shift off your attendance at this Parliament.
 
 That was unmistakable: his life was in danger.
 
 What would Rollo say in such a message? Something pious, perhaps.
 
 For God and man have concurred to punish the wickedness of this time.
 
 That seemed to have the right apocalyptic tone.
 
 And think not slightly of this advertisement, but retire yourself into your country where you may expect the event in safety.
 
 She needed to say something about the means by which the killing would be done. But all she knew was that Ned thought they planned to set the building on fire. She should hint at something like that.
 
 For though there be no appearance of any stir, yet I say they shall receive a terrible blow this Parliament. And yet they shall not see who hurts them.
 
 What else would a conspirator think about? Destroying the evidence?
 
 This counsel is not to be condemned because it may do you good, and can do you no harm; for the danger is past as soon as you have burned the letter.
 
 And how should she end? With something sincere, she decided.
 
 And I hope God will give you the grace to make good use of it: to whose Holy protection I commend you.
 
 She folded the letter and sealed it, pressing a coin into the soft wax and wiggling it a bit to make the impression unreadable, as if a seal ring had been carelessly applied.
 
 Now she had to deliver it.
 
 She would probably be seen by people at the house, and perhaps by Monteagle himself, who knew her, so she needed a disguise.
 
 Margery and Ned employed a maid-of-all-work who was at present washing sheets in the backyard. Margery told her to take the rest of the day off and gave her sixpence to go to the bear-baiting.
 
 She went to Ned’s wardrobe. She put on a pair of his breeches, tucking her petticoats inside for bulk, and then a frayed old doublet. Ned was slim, but, nevertheless, his clothes were too big for her. However, a mere messenger would be expected to be badly dressed. She put on a worn-down pair of his shoes and stuffed them with rags to make them fit. Her ankles were too small for a man, she saw. She pinned up her hair and put on Ned’s third-best hat.
 
 It would be awkward if Ned were to come home now. But he would almost certainly be out all day: work would have piled up on his table while he was in Paris. And he was supposed to have dinner at Cecil’s house. The likelihood of a surprise return was low – she hoped.
 
 In the mirror she did not look much like a man. She was too pretty, and her hands were too small. She put a coal shovel up the chimney and brought down a quantity of soot, then used it to besmirch her hands and face. That was better, the mirror told her. Now she could pass for a grubby little old man of the kind who might well be used as a messenger.
 
 She left the house by the back door and hurried away, hoping that any neighbours who glimpsed her would not recognize her. She went east to Ald Gate, and passed through it out of the city. She walked through fields to the village of Hoxton, where Monteagle had a suburban house in a large garden. She went to the back door, as a scruffy messenger would.
 
 A man with his mouth full of food came to the door. She handed the letter to him and said in her gruffest voice: ‘For Lord Monteagle, personal and very important.’
