Puzzled, she looked up at Agnes for an explanation.

“It is Gerda. There in the front row,” she said, pointing.

Sarah looked again and recognized Gerda Reinhard. She was sitting with a young man in a bowler hat. He had his arm around her, and they were obviously only pretending to be frightened. “Where was it taken?”

“At that place, what do they call it? It is on an island…”

“Coney Island?” Sarah asked, looking at the photograph again.

“Ja, Gerda said they have this boat ride. The boat goes down a… a hill and makes a big splash.”

“And they take a photograph of it?” Sarah knew that couldn’t be true. Photography required that the subjects sit very still. Taking a picture of an amusement-park ride would be impossible.

“Yes,” Agnes said, “but not when it is going.” She searched for the proper words to explain. “They have a special boat. That one,” she added, pointing to the picture. “You sit in it, and they make a photograph. The people in the boat are just pretending to be riding down the hill.”

“Oh, I see, so they have a souvenir of their adventure,” Sarah said, looking more closely at the picture. “Do you know the man sitting with Gerda?”

“No, we do not, and that made Lars very angry. He say Gerda should not be making photographs with men he does not know.”

Sarah only wished Gerda had only been posing for photographs with such men. That was the least of her transgressions.

“At least you have her picture,” Sarah pointed out. “To remember her by.”

“But such a picture,” Agnes lamented, closing her eyes again.

Sarah discreetly finished examining the contents of the box, carefully replaced the lid, and set it back where she had found it. Maybe she could ask Lisle and the other girls if they knew the man in the photograph, although the chance that he was Gerda’s killer was probably remote.

“That was the day when she got the red shoes,” Agnes murmured, her eyes still closed so that Sarah wasn’t sure if she’d been addressing her or not.

“Gerda got the red shoes when she went to Coney Island?” Sarah asked.

Agnes nodded, her face a mask of pain. “Just before she…”

“Agnes, would you mind if I borrowed this photograph for a few days? I’d like to see if I can find out who this man with Gerda is.”

Agnes’s eyes flew open, and her pain instantly turned to horror. “Do you think he is the one?”

“That’s something we can let the police find out,” she demurred.

Malloy would be proud of her restraint. She’d have to make sure he heard about it very soon.

MALLOY CALLED ON HER IN THE MIDDLE OF THE afternoon. He figured this would be the best time. She wouldn’t try to feed him, so he wouldn’t have to stay very long. He just needed to repay the debt he owed by telling her what he knew about the German girl’s death, and then he’d be free of her for good.

It was a good plan. Why did he have such a sickening feeling it wouldn’t be quite that simple?

The moment she opened the door to him, he knew he should have let her know he was coming. Because of the heat, she was wearing hardly any clothes at all. Well, she did have a dress on, but her arms were bare, and the dress was so light, it left little of her figure to the imagination. He wondered she considered it decent. He certainly didn’t.

“Malloy,” she said, the way she always did, and smiled. The way a cat smiles when it’s been in the cream. “Come in. I was visiting with my neighbor, Mrs. Elsworth, but I’m sure she’ll excuse us. Like your mother, she thinks there’s something more between us than a mutual interest in a murder case, and she’ll be only too happy to leave us alone.”

Plainly, she found this amusing. Malloy did not.

She left him no choice but to follow her out to her backyard. The old woman from next door was sitting there, fanning herself with the most elaborate fan Frank had ever seen. Her wrinkled face lit with happiness when she saw him.

“Detective Sergeant Malloy, Mrs. Brandt didn’t tell me you were expected. I’ll take myself off so you two can discuss… uh… whatever it is you need to discuss,” she said with a sly grin.

“That’s kind of you, ma’am,” Frank said, wishing he didn’t feel embarrassed. He had nothing to feel embarrassed about. This meeting was strictly business.

The old woman rolled her eyes as she gathered her things to leave. “I guess I should’ve expected Mr. Malloy. I broke a needle today, you know. And yesterday I saw three crows together.”

Mrs. Brandt smiled patiently… “Does that mean a visitor is coming?” she asked.

“Oh, no,” Mrs. Elsworth said smugly. “Both those things mean a wedding. I’ll be off now. You two enjoy your afternoon.”

As soon as the old woman had disappeared through the gate connecting the two yards, Mrs. Brandt said, “Don’t look so terrified. Her omens hardly ever come true.”

“I’m not-” he began, then caught himself. He wasn’t going to get into a conversation about that. He cleared his throat. “I talked to the detective who’s investigating the girl’s death,” he said instead, figuring that would distract her.

It did. “Sit down and tell me everything,” she said eagerly. “I’ve found out some things, too.” She took the other chair and began to pour some lemonade from a pitcher. “Take your jacket off. You must be sweltering.”

Frank briefly considered doing so. He was sweltering, but he didn’t want to start getting comfortable with Sarah Brandt. He wasn’t going to know her that much longer. Besides, his shirt was probably badly wrinkled.

He did sit down, though, and he did drink the lemonade she offered him. Then he took out his handkerchief and mopped his brow and for just a moment allowed himself to enjoy the cool shade of her yard and the sweet scent of her flowers. But only for a moment.

“Bill Broughan is investigating the case,” he began.

She nodded. “I remember him. I tried to get him to tell me where you lived, but he wouldn’t do it. He said it would be worth his life, if I recall correctly.”

“He’s the one,” Frank confirmed.

“Is he any good? As a detective, I mean?”

“When he’s sober.”

“Which isn’t very often, I’d guess.”

She was right about that. No need to tell her, either. “He said the girl was out dancing every night. Went with a lot of men. Didn’t have a steady fellow, so there’s no telling who she was with that night.”

“Even her friends don’t know, the ones who were with her at Harmony Hall,” she confirmed.

He looked at her in surprise. “Harmony Hall?”

“It’s a dance hall on Fourteenth Street, over a saloon. That’s where she went dancing the night she died.”

“If you knew all this, why do you need me?” He was feeling annoyed, although he knew that was irrational.

“Because I didn’t know it when I saw you last. I met Gerda’s friends at her funeral, and they told me all this. I feel sure the police have uncovered a lot more about her, though. What else did you find out?”

“Nothing,” Malloy admitted reluctantly. “You might as well forget finding who killed her. Nobody is going to bother to investigate.”

“They’re giving up already?” she asked, outraged.

“I told you, there’s no way to find out who killed her. There’s just too many possibilities.”

“What if I could help you narrow it down to a few?” she asked slyly.

Frank didn’t like that expression one bit. “How?”

“Someone gave Gerda a hat shortly before she died. His name is George, he spends a lot of time at dances, and he sells ladies’ furnishing. Someone else gave her red shoes, someone who was with her at Coney Island, and I have a photograph of him. Wait right here. I’ll get it.”

Frank felt like he’d been poleaxed. The woman was a caution. How on God’s earth did she get a photograph of the killer?
