silenced her.
The two of them retreated once again to their bedchamber.
âWhat can we
do
?â asked Eliza.
They sat on the bed, and Lucy took out her notebook and read through everything she had written down.
âMouserâ¦â she said at last.
â
Mouser?
â
âMouser goes exploring in the coal store⦠And John Johnson is storing fuel in the big cellar under the House of Lords⦠And â do you remember? â Mistress Rowley said there used to be a way into that big cellar from this houseâ¦â
Eliza understood â and felt excited. âSo, if we follow Mouser, we might find the way in?â

On Mouserâs Trail
They waited till night â when everyone had gone to bed, even Mistress Rowley and the maids.
âThe servants work late,â said Eliza, âand Bessy â sheâs the youngest maid â she sleeps in the kitchen.â
They listened to the household sounds: doors closing, footsteps on the stairs, murmured âgoodnightsâ from the family.
Outside, in the street, the watchman passed by with his lantern. âTen oâclock, and allâs well!â he called.
Still they waited, dressed in their nightgowns, and sitting up straight so as not to fall asleep.
At last the house fell silent except for creaking timbers and the scuttering of mice in the wainscot.
âLetâs go,â whispered Eliza.
They crept downstairs.
The kitchen was dark, and they paused in the doorway until their eyes became accustomed to the gloom. The fire was banked up, and in front of it Bessy lay asleep on a pallet. They tiptoed past her.
Eliza gasped as she felt the brush of a furry body on her legs and heard a faint âprrrowâ¦â
Mouser trotted towards the open storeroom doorway.
âQuick!â whispered Lucy.
They followed the cat into the storeroom as he padded past shelves laden with cleaning materials and tools. Further in Eliza could see the coal store and, next to it, bundles of firewood piled up and stacked against the wall. Mouser disappeared behind the stack.
The girls crouched and followed him, crawling on hands and knees. Elizaâs sleeve caught on a nail and she felt it tear.
Now Iâll be in more trouble
, she thought.
âLook!â Lucyâs voice was full of suppressed excitement.
Eliza peered, and saw a door. There was a big hole in it near the base, where the wood had rotted â and disappearing through the hole was Mouserâs tail.
âIt must be the door to the big cellar,â said Lucy. âThe one Mistress Rowley said hadnât been used for years.â
They tried the handle. âItâs locked,â said Eliza.
She knelt and pushed her head and shoulders through the hole.
âWhat can you see?â asked Lucy.
âNothing. I can feel a stone floor â oh, and walls. Itâs a passage!â
She came back out, and they looked at each other. Eliza wondered if Lucy felt as scared as she did. She took a breath. âShall we go in?â
They crawled through â Eliza first, then Lucy â and stood up. The stone floor of the passage sent a chill up through their silk slippers and they shivered in the cold air. Eliza felt for Lucyâs hand as they moved forward.
To their relief, the passage was short. Almost at once they became aware of a faint greyish light and reached another door.
There was no sound from Mouser, and they could not see him. He must have found a way in.
âHe went underneath,â Eliza whispered. âLook! The whole bottom of the door has rotted away. But the gapâs too small for us.â
She wrenched at the damp, crumbly wood, and a big piece broke off, startling her.
Both girls froze. What if someone was there, on the other side, watching?
But Eliza heard nothing. Cautiously they enlarged the gap some more, and then Lucy, who was thinner than Eliza, began to squeeze herself through.
