Number 67 was opposite but not directly opposite. In a confusing old London way the numbers on this street ran consecutively and started back on themselves to complete the tour. Number 67 had a green front door, as did several others in the street, and like number 42 it passed Lily’s clean window test.

With a confident smile, she approached the children. She grabbed Little Lord Fauntleroy from behind and, carrying his slight weight in front of her, she began to hop the chalked grid, bouncing his feet on each of the squares and chanting the rhyme as she went.

‘Five, six, seven, this way to heaven. Eight, nine, ten, turn round again.’ She reached the top and hopped back. ‘Three, two, one, you’ve had your fun!’ She deposited the giggling child on his feet at the start.

‘Again! Again!’ he shouted, holding up his arms.

Lily obliged.

Fighting for breath she addressed the oldest boy, distinguished by his sailor collar. ‘I wonder if you can help me?’

They stared at her with surprise and suspicion. No one replied. Instead they gathered together in a huddle and the big boy appeared to be laying down the law. His sister defied him. ‘Naw! Gerraway, Jim! She’s never! Look at ’er! Seccetary or somefin’ – that’s what she is. An’ anyway – rozzers i’n’t women. An’ if they woz they’d never play hopscotch.’

Emboldened, Jim looked her up and down and asked: ‘You the law, miss? You with the rozzers? We don’t talk to them … Dad’d tan our arses.’

Lily was affronted. ‘Crikey, no! I’m looking for digs. Secretary as you guessed, miss!’ Lily beamed at the little girl. ‘I’ve just got a position in a solicitor’s office … Crabtree and Bingham at the end of the road. A friend of mine lives hereabouts … she’s going to help me find a respectable place to stay. I’ve just got in to Paddington this morning. Only I’ve lost the number she gave me. I’m sure this is the right street and she said it had a green front door.’

The children relaxed. ‘Oh, that’ll be Mrs Royston’s at number sixty-seven.’ They all pointed. ‘She takes gels in.’

‘And she’ll have a room spare. She’ll be looking for someone to fill the upstairs front now,’ the girl added knowingly. Head on one side contemplating the stranger, she came to a decision, grinned and confided: ‘Don’t offer her a penny more than five bob a week, all in. She’s a mean old bat. She’ll screw more out of you if you don’t stand up for yourself.’

‘Well, thanks for the advice!’ Lily said cheerfully. She lowered her bottom to perch casually on the window ledge of number 42 and took off her hat as a gesture of ease. The children gathered round, intrigued. ‘I wonder if you know my friend? She’s called Anna and she’s got dark hair and she’s very pretty. She works up west in a big hotel.’

Their faces fell and they looked at each other again. Finally, the girl offered: ‘Well, you’re out of luck. Annie’s gone. Legged it. Right after the rozzers was ’ere.’

‘No! You must have got that wrong. Annie’s never in any trouble … she’s a good girl, Annie. Hard worker. Honest as the day is long. I’d go bail for her any day.’

‘Oh, she’s in trouble all right,’ the boy said portentously. ‘Five of them there were. Four uniform and one in plain clothes. Knocked us up before six. Ma and Pa were having their breakfast. Ethel and me – we listened on the stairs. Wanted to know where a certain Anna Peterson was, they said. Come over real nasty when Pa told ’em where to get off.’

‘Pa don’t like the law,’ the girl explained. ‘No one round here does. Always on the take. Bent as a hairpin, my ma says. They banged Pa up in the nick once. Fitted him up for receiving. He never deserved it. It were only a dish o’ tripe as no one else wanted. He don’t forget! Sent ’em off with a flea in their ears.’

‘Good old Pa,’ said Lily. ‘That’s the stuff to give ’em. And they had no idea where Annie was?’

‘Naw! They banged on a few doors …’ Jim indicated the houses on either side and immediately opposite, exactly the houses Lily would have tried herself if she’d been on police duty, ‘but nobody in this street’d split. “Don’t know nuffin’! No idea what you’re on about!” that’s what they all said. Even crabby old ’erbert at number sixty-five told ’em to sling their ’ook. They never tried Mrs Royston’s. Annie got clean away. She must have heard the ruckus. Waited an hour and ten minutes, she did, before she done a runner.’

‘But how do you know she was leaving, Jim?’

It was Ethel who answered. ‘We were here in the street. She came to her window. Up there, miss. And she waved to us. And blew us a kiss. She had her hat and coat on.’

‘And did she say anything as she passed you?’

Looks of scorn greeted this question. ‘Naw! She never passed down here,’ said Jim. ‘More sense. She’ll have gone out the back way. Over the yard and across the allotments, turn left and you’re in the Church Street.’

Lily began to see a further advantage of a roost in Hogsmire Lane.

‘We waved back. We wished her good luck,’ Ethel said with a touch of defiance. ‘She was a nice girl, miss, your friend. Gave us all a lollipop every Saturday. I’ve still got mine that she gave me yesterday.’ The little girl rubbed her eyes with the hem of her pinny and began to sniff.

‘She may come back when the bother – whatever it is – has blown over,’ Lily said. ‘She’ll be glad you stuck up for her. And look – I think my friend would like you to have this.’ She took a sixpenny bit from her pocket and handed it to the girl. ‘You can be quartermaster, Ethel. Next Saturday’s lollipops. In case she’s not back in time.’

As the small silver coin disappeared with coos and muttered thanks into the depths of Ethel’s pocket, Lily put her hat back on and stood up. ‘Well – I can see I shall have to go back to Paddington and pick up my suitcase before I knock on Mrs Royston’s door. Landladies don’t take kindly to females who appear with no luggage on their doorsteps and I see this is a very respectable part of town. A good five bob’s worth! Keep your eyes peeled for the rozzers, kids! Especially the ones with the moustaches. They’re the nastiest.’

Chapter Twenty-Eight

Joe was uneasy. He prowled about his office closing drawers and straightening pictures. He tapped the wall clock and checked it against his wristwatch. They agreed that it was now two o’clock. Where’d she got to? He’d quite forgotten to tell her they were expected at Cassandra Dedham’s house for tea. Would she make an appearance back at the Yard in time to accompany him?

A phone call had come from Princess Ratziatinsky at noon to say that Wentworth had left. He wanted to finish up at the Yard, close his files and get something to eat. He’d had time for a shower and a cup of tea and a change of clothes back at his flat just before dawn but since then had been chained to his desk, listening to reports and moving his men around. He’d told her to take a taxi back. A ten-minute drive.

Common sense reasserted itself. She’d probably nipped off to visit her parents and tell them all her adventures. Sunday. It was her day off. She’d completed her self-imposed task and was clearly at liberty to spend the rest of the day as she wished. Yes, that’s what London girls did on the Sabbath, after all – they went back home for luncheon with Ma and Pa. The traditional slice of roast beef, no doubt. Apple pie to follow? A pang of hunger hit him and he dealt with it.

Hunger and lack of sleep he’d learned to accommodate in his war years. He hadn’t expected he’d need those skills working at a desk job. He allowed himself a momentary tight grin. He would never accept an easy existence. Too many mischief-makers to be brought to account; too many scores to settle. This blasted Morrigan, for one. The woman should have been under lock and key by now. She was running rings round him. A slight but unmistakable feeling of dry-mouthed giddiness disturbed him. He recognized it for the moment of controlled terror before the whistle blew. A warning he should heed?
