It’s been four years since we last spoke. We kept in touch for the first few months after we got back from Nepal, talking on the phone every day, trying to make sense of what had happened, but then Al sold her story to the press and everything changed. I couldn’t understand why she’d done it. I called her, over and over again, begging her to explain why she’d gone back on what we’d agreed, but she ignored my calls. I don’t know if it was the money or the attention or what, but it was the worst kind of betrayal, especially after everything we’d been through.

I hold down the delete button and the cursor zips from right to left, swallowing the message I’ve been trying to compose for the last half an hour. I start again:

Al, it’s me.

No. I created this Facebook account as Jane Hughes, and she won’t know who that is.

Al, it’s Emma. I know you probably don’t want to talk to me, but I need your help.

I delete the last sentence.

Al, it’s Emma. I think Daisy’s still alive. Please contact me. Here’s my mobile number …

I touch the button beneath the swipe pad, ready to click send, but then change my mind again. Does she already know? Whoever typed the message onto the Green Fields’ website could already have contacted Al. If I found her in minutes, they could have, too.

I reach for my mobile and click on Will’s name. The call goes straight to voicemail. His tone is professional and impersonal but the sound of his voice is comforting.

“Hi, Will, it’s Jane. Could you give me a ring when you finish school? I need to talk to you; it’s important.”

I place the phone on the desk next to the laptop. I stare at the screen, drumming my right index finger on the button under the swipe pad.

Delete or send? Delete or send? My heart tells me to trust Al. My head says not to.

I click send.

The second Will sets eyes on me, he gathers me into a tight hug.

“Sorry, darling. I thought I’d mentioned that it was parents’ evening tonight.” He pulls away, his hands on my shoulders. “You okay? You sounded worried on the phone.”

“Yeah … I …” I hand him a bottle of red wine. “I’ve had a bit of a weird day and …” The sound of two people talking drifts towards us as a couple of dog walkers stroll past the end of Will’s garden, their high-visibility jackets glowing in the light from the house. “Can we talk inside?”

“’Course, yeah.” He reaches an arm around my shoulders and ushers me into the house.
