‘His face looks very … pink.’ Zinia voice was almost accusing. She peered again at the body. ‘Can you assure me that he’s perfectly dead?’

‘He is, indeed, madam. You have my commiserations. And my assurance that we did everything we could.’

‘Madam, I am most dreadfully sorry … Dr Thomas Tenby at your service. My card.’

‘Thank you, doctor. I am grateful for your efforts.’ Zinia was recovering her haughty demeanour. Still held firmly by Lily, she stared down at the body again.

‘Why don’t you take a seat, madam?’ he said, taking in at last the girl’s emotional exhaustion and dishevelled state. ‘You’ve had a frightful shock.’ He led her over to a chair away from the table, then whispered in Lily’s ear: ‘Tate. Leave this and get him in here, will you? He’s needed.’

The scene of crime photograph. Lily didn’t have to search for Cyril. He was standing, equipment in hand, just outside the folding doors, arguing with a footman. She pulled him inside.
