‘Yes,’ answered Buckingham.

Cranston bent down, crouching to look at it, nodded and rose.

‘And the corpse?’

Lady Isabella gulped at his harshness. Sir Richard led them over, pulling back the heavy bed curtains. The huge four poster bed had been stripped as a pallet for Springall’s corpse which lay rigid and silent under a leather sheet. Cranston pulled back the cloth. Now Athelstan had seen many a corpse, male and female, with the most horrible injuries, yet he thought there was something nightmarish in seeing a man in his bed, dressed in his nightshirt, eyes half open, mouth gaping like a landed fish. When alive Sir Thomas must have been a fine-looking man with his tawny hair, sharp soldier’s face and military appearance. In death he looked grotesque.

Cranston sniffed the man’s mouth and gently pushed back the lolling head. Athelstan watched fascinated, noting the slight purplish tinge in the corpse’s face and sunken cheeks. Someone had attempted to close the dead merchant’s eyes and, unable to, had placed a coin over each of his eyelids. One of these had now slipped off and Sir Thomas glared sightlessly at the ceiling. Cranston turned, waving Athelstan closer to examine the body. He always did this. The friar suspected Cranston took enjoyment in making him pore over each corpse, the more revolting the better. Athelstan pulled back the nightshirt and examined the rest of the body, impervious to the groans and gasps behind him. He looked over his shoulder; Lady Isabella had walked back towards the door, Sir Richard’s arm around her waist. Buckingham just stood with eyes half closed. Both merchants looked squeamish, as if they were about to be sick. Outside the Nightingale Gallery sang and Lady Ermengilde, her hands grasping a black stick, her face covered in a fine sheen of sweat, pushed into the room and glared at Cranston.

‘Is this necessary?’ she asked. ‘Is it really necessary?’

‘Yes, Madam, it is!’ he barked in reply. ‘Brother Athelstan, have you finished?’

The friar examined the corpse from neck to crotch. No mark of violence, no cut. Then the hands. They had been washed and scrubbed clean, the nails manicured. The body was now ready for the embalmer’s, before being sheeted and coffined and the funeral ceremony carried out.

‘Poison,’ Athelstan confirmed. ‘No mark of any other violence. No sign of an attack.’

Athelstan picked up the cup and sniffed it. The smell was rich, dark, dank and dangerous. It cloyed in his mouth and nostrils. He put it down quickly and bent over the corpse, sniffing at the dead man’s mouth from which issued the same acrid, richly corrupting smell.

‘Belladonna and arsenic?’ Athelstan remarked.

Buckingham nodded.

‘A deadly combination,’ the friar observed. ‘The only consolation is that Sir Thomas must have died within minutes of putting the cup down. Sir John, you have seen enough?’
