Athelstan took his cloak and braved the freezing weather. Night was edging in. Daylight was swiftly fading. The Tower garrison was preparing for sleep. Figures and shapes slid through the ever-present mist. Athelstan glanced towards Beauchamp where torches flared above the doorway, gleaming on the armoured mail of the guards. ‘I wonder who you really are?’ Athelstan whispered to himself. He made his way across the icy ground into the White Tower, up the stairs and into St John’s Chapel. Cranston, Lascelles, Cornelius, Rosselyn and the Straw Men were gathered there. Athelstan smiled to himself. The coroner had exercised his authority. The chapel itself hadn’t changed much since the day of the killing. The heavy tapestry curtains still hung between the pillars on either side, screening off the aisles or transepts where the food tables had stood. The bloodstained turkey carpet and matting had been removed but Hell’s mouth still stood wedged into the entrance of the rood screen. On either side of this hung the heavy arras concealing the left and right aisles flanking the sanctuary. Athelstan stared around and, ignoring the hubbub of conversation, walked out of the chapel, down the steps and into the cold darkness of the crypt. He took a cresset from its holder and went along to the far window. He stared at this then crossed to the small recess where Barak’s body must have lain. Athelstan was convinced Barak was no assassin. He’d either been killed or felled unconscious here, then swiftly dragged up, the arbalest and war belt used to depict him as such. Those shutters had been opened and Barak’s body violently hurled out. He heard raised voices so he walked back up the steps to join the rest in St John’s Chapel.
Cranston had persuaded Rachael to act as Oudernarde, Samuel as Lettenhove. The rest of the Straw Men were arguing about where they were on that day. The others were just as vague about their whereabouts, especially Rosselyn and Cornelius, who never mentioned anything about their swift departure from the chapel to check on Beauchamp Tower. Eventually Cranston imposed order. He reached a consensus that Oudernarde and Lettenhove had been standing on opposite sides of the chapel.
‘As were the two braziers when the small explosions occurred,’ Cranston declared. ‘They caused the first confusion, then Lettenhove was struck, followed by Oudernarde. Yes?’ They all murmured in agreement. ‘And the assassin,’ Cranston pointed down the chapel towards the door, ‘could not have stood or knelt there; he would have been glimpsed by the guards or the musicians, yes?’ Again, everyone agreed.
‘In the aisles either side,’ Samuel offered but then shrugged as he realized the foolishness of what he had said.
‘The killer,’ Cranston answered, ‘if he had stood in the aisles, would be in full view of all those pressing around the food tables. The assassin first loosed at Lettenhove then somehow moved across the chapel to release a second bolt at Meister Oudernarde. And that,’ the coroner wagged a finger, ‘is the mystery. How could this assassin carry, prime and loose not one crossbow bolt but two then hide his weapon, all without being seen?’
‘Not to mention producing those two severed heads,’ Athelstan intervened. He walked to the rood screen, gesturing with his hands to either side. ‘Both are found halfway along either side of Hell’s mouth. Of course,’ Athelstan pulled at the arras on the right side of the rood screen, ‘the assassin may have hidden behind this, loosed the bolt then moved swiftly across the sanctuary behind Hell’s mouth to the other arras and done the same again, then pushed out those two heads. And yet for one person this would be difficult, very difficult.’
‘And we were there,’ Rachael spoke up. ‘I’m sure we were, collecting costumes, masks and other items.’
‘And I went behind to check all was well.’ Rosselyn, crouching at the foot of a pillar, spoke up. ‘I saw nothing untoward.’ He rose clumsily to his feet. ‘And remember the crossbow was never found.’ Athelstan did not answer him; he was desperately trying to recall what had been happening when those crossbow bolts had been loosed. He pointed to one of the polished oblong tables on which the food had been served.
‘Please, if you could bring one of those over here.’
Samuel and Rosselyn did, moving chairs and putting the table down in the centre of the chapel. Athelstan asked them to gather around.
‘Look,’ he smoothed the top of the table with his hand, ‘the chapel of Saint John is a rectangle stretching west to east. On the eastern side here,’ Athelstan pointed to the top of the table, ‘stretches a line which includes the rood screen and the arras hanging either side. The entrance through that rood screen is blocked by Hell’s mouth.’
