“Enough stupid bravery. Call the police,” Belinda hissed and I couldn’t help but agree with her. We crept to the phone and dialed 999, then waited clinging on to each other as if we were in a storm-tossed ocean. At last I thought I heard shouts and a scuffle and then a thunderous knock at our front door. I opened it a crack and saw with relief two constables standing there.

“We’ve caught someone snooping around your house, my lady,” one of them said. I recognized him as the constable from the other night.

“Good work, Constable. It may be the man who broke in and killed the Frenchman. Where is he?”

“Bring him over here into the light, Tom,” my constable instructed.

A fellow constable appeared, forcing in front of him a man in a raincoat.

I looked at him and let out a shout. “Granddad! What are you doing here?”

“You know this man, my lady?”

“It’s my grandfather.”

He released Granddad. “Sorry, sir, only the young lady called us to say she heard noises outside.”

“No offense, Constable. My granddaughter had no idea that I’d be here.”

“I’m glad you are here now,” I said. The constables departed and Granddad came inside. We all poured ourselves another Scotch to calm our nerves and sat in the morning room.

“What were you doing here?” I asked. “You scared us to death when we saw your shadow outside.”

He looked sheepish. “I was worried about you, so I decided to come and keep an eye on you. Just in case.”

“You think I’m in danger?”

He nodded. “Listen, my love. I’ve lived in London all my life and I can only think of one or two accidents on the tube lines. People don’t fall off platforms very easily.”

“What do you mean?”

“I mean that somebody might be trying to kill you.”

“Kill me—why?”

“I’ve no idea, but it did cross my mind that the person who murdered that Frenchie might have thought he was killing your brother.”

“Oh, surely not.” Even as I said it I realized that they were about the same build.

“Well, I for one am glad that your grandfather is here,” Belinda said, getting up and yawning. “Let’s make a bed up for him and we can all get some sleep.”
