We should depart at once.’
They walked single file through the houses behind Albermap Crescent, Phelps in the lead, then the Doctor and Miss Temple, Mr Brine at the rear. Mr Cunsher had stayed to feed all evidence of their inhabitation to the stove. He would join them further on.
‘Why can we not simply return to the Boniface?’ asked Miss Temple.
‘Because I do not care to deliver myself into my enemy’s hand,’ Phelps whispered without turning. He waved them through a battered wrought-iron gate. ‘Keep low … do not speak … with any luck no one will see …’
Beyond the gate lay shuttered houses, riven walkways choked with weeds and an open common. Through the darkness Miss Temple perceived a host of canvas tents and winking lanterns, and snatches of talk in other tongues. Svenson took her hand. She wondered if she ought to take Mr Brine’s, so no one would be lost, but did not. A dog barked near one of the tents, and achorus of yaps rose all around. The party broke into a run, outpacing the human calls that followed the dogs, challenges sent out to passing ghosts.
Their way ended at a high stone wall. Phelps began patting at it like a blind man. Miss Temple looked back. The dog had again provoked the chorus of its fellows.
‘I expect that’s Mr Cunsher,’ whispered Brine.
‘Who
is
Mr Cunsher?’ Miss Temple asked.
‘A man known to the Ministry,’ said Svenson. ‘You would call him a spy.’
‘But not from
here
.’
‘No more than you or I, which recommends him, this city being a snakepit … ’
Miss Temple realized the Doctor had quietly drawn the Naval revolver.
‘At last … at
last
,’ muttered Phelps, and she heard the turn of a key. ‘Quickly, inside and up the stairs.’
‘A relic of an older time.’ Phelps’s whisper rebounded off a brick ceiling. He tamped the lamp wick to a lower flame and slid a fluted glass over it. ‘A portion of ancient city wall – a tower left to secure river traffic, and then left again as a useful hole for stuffing things and people one’s government ought not to have. I learnt of it from the late Colonel Aspiche, who stumbled across it as a subaltern. Once assigned to Palace duties, he sought out the key … a key which I took it upon myself to, ah, take.’
‘Colonel Aspiche was horrid,’ said Miss Temple.
Phelps sighed. ‘I am sure you must have found him so – as you must find me. Ambition has made apes of better men, and far worse.’
‘How do you
feel
?’ asked Miss Temple, not interested in another apology. ‘The sickness from the blue glass – has it passed? Are its effects reversed?’
‘In the main, though not without cost – I do not think I shall ever sleep the night through without some dream of
her
staining my mind. If Doctor Svenson owes his life to my efforts, I owe my sanity to his.’
Svenson smiled tightly, snapping open his silver case for a cigarette. ‘You ask what I have done these weeks, Celeste, apart from tending my own wounds. Do you still have the orange metal rings? Cardinal Chang stuffed a quantity into my pocket – I assume he did the same to you.’
Miss Temple flushed at the memory of Chang’s fingers thrusting into the bosom of her dress, for it had become a fixture of her intimate relief. Svenson hesitated at her silence, but then went on. ‘The qualities of this orange mineral counter those of the blue glass; thus the rings enabled each of us to resist the powers of Mrs Marchmoor. You will remember the liquid we used to cure Chang’s wounds in the airship. I was able to distil a kind of tincture from my supply of rings. Crude, to be sure, yet it minimized the poison in Mr Phelps. With time and proper tools I could do more – if I knew what the alloy
was
, I could do more still.’
He knelt and studied her face. ‘The glass woman rummaged in your thoughts too. At the factory, you appeared nearly consumptive …’
She turned from his gaze. ‘I have made a point since to eat fresh
