She came up to me swiftly and eagerly, moving with that strange lissom grace that always reminded me of some untamed animal. Her hurried walk across the marsh had brought a faint tinge of colour into the usual ivory clearness of her skin, and her dark eyes were alive with excitement.

I held out my hands to welcome her. "I was beginning to think you'd forgotten the address, Sonia," I said.

With that curious little deep laugh of hers she pulled my arms round her, and for several seconds we remained standing in this friendly if a trifle informal attitude. Then, perceiving no reasonable alternative, I bent down and kissed her.

"Ah!" she whispered. "At last! At last!"

Deserted as the marsh was, it seemed rather public for this type of dialogue, so drawing her inside the hut I closed the door.

She looked round at everything with rapid, eager interest. "I have heard all about the powder," she said. "It's quite true, isn't it? You have done what you hoped to do?"

I nodded. "I've blown up about twenty yards of Canvey Island with a few ounces of it," I said. "That seems good enough for a start."

She laughed again with a sort of fierce satisfaction. "You have done something more than that. You have given me just the power I needed to help you." She came up and with a quick impulsive gesture laid her two hands on my arm. "Neil, Neil, my lover! In a few hours from now you can have everything you want in the world. Everything, Neil—money, freedom, love—" She broke off, panting slightly with her own vehemence, and then drawing my face down to hers, kissed me again on the lips.

I suppose I ought to have felt rather ashamed of myself, but I think I was too interested in what she was going to say to worry much about anything else.

"Tell me, Sonia," I said. "What am I to do? Can I trust your father and McMurtrie?"
