I figured “pulled a Jack the Ripper” was one of those English expressions I’d need to learn. I’d been studying them online so I wouldn’t get confused when people started talking to me about “quid” and “Jammy Dodgers” and things like that. This one had not crossed my electronic path.

“Oh,” I said. “Sure.”

He led me through the crowds of people trying to get into the elevators that took us up to the parking lot. As we left the building and walked into the lot, I felt the first blast of cool breeze. The London air smelled surprisingly clean and fresh, maybe a little metallic. The sky was an even, high gray. For August, it was ridiculously cold, but all around me I saw people in shorts and T-shirts. I was shivering in my jeans and sweatshirt, and I cursed my flip-flops—which some stupid site told me were good to wear for security reasons. No one mentioned they make your feet freeze on the plane and in England, where they mean something different when they say “summer.”

We got to the school van, and Mr. Franks loaded the bags in. I tried to help, I really did, but he just said no, no, no. I was almost certain he was going to have a heart attack, but he survived.

“In you get,” he said. “Door’s open.”

I remembered to get in on the left side, which made me feel very clever for someone who hadn’t slept in twenty-four hours. Mr. Franks wheezed for a minute once he got into the driver’s seat. I cracked my window to release some of the cologne into the wild.

“It’s all over the news.” Wheeze, wheeze. “Happened up near the Royal Hospital, right off the Whitechapel Road. Jack the Ripper, of all things. Mind you, tourists love old Jack. Going to cause lots of excitement, this. Wexford’s in Jack the Ripper territory.”

He switched on the radio. The news station was on, and I listened as he drove us down the spiral exit ramp.

“. . . thirty-one-year-old Rachel Belanger, a commercial filmmaker with a studio on Whitechapel Road. Authorities say that she was killed in a manner emulating the first Jack the Ripper murder of 1888 . . .”

Well, at least that cleared up what “pulling a Jack the Ripper” meant.

“. . . body found on Durward Street, just after four this morning. In 1888, Durward Street was called Bucks Row. Last night’s victim was found in the same location and position as Mary Ann Nichols, the first Ripper victim, with very similar injuries. Chief Inspector Simon Cole of Scotland Yard gave a brief statement saying that while there were similarities between this murder and the murder of Mary Ann Nichols on August 31, 1888, it is premature to say that this is anything other than a coincidence. For more on this, we go to senior correspondent Lois Carlisle . . .”

Mr. Franks barely missed the walls as he wove the car down the spiral.
