the gates of the palace every day, but most of them needed the things to be opened first.
The guards on the other side were rigid with fear, because they thought they had seen a ghost.
They would have been far more frightened if they had known that a ghost was almost exactly
what they hadn't seen.
The guard outside the doors of the great hall had seen it happen too, but he had time to gather his
wits, or such that remained, and raise his spear as Binky trotted across the courtyard.
'Halt,' he croaked. 'Halt. What goes where?'
Mort saw him for the first time.
'What?' he said, still lost in thought.
The guard ran his tongue over his dry lips, and backed away. Mort slid off Binky's back and
walked forward.
'I meant, what goes there?' the guard tried again, with a mixture of doggedness and suicidal
stupidity that marked him for early promotion.
Mort caught the spear gently and lifted it out of the way of the door. As he did so the torchlight
illuminated his face.
'Mort,' he said softly.
It should have been enough for any normal soldier, but this guard was officer material.
'I mean, friend or foe?' he stuttered, trying to avoid Mort's gaze.
'Which would you prefer?' he grinned. It wasn't quite the grin of his master, but it was a pretty
effective grin and didn't have a trace of humour in it.
The guard sagged with relief, and stood aside.
'Pass, friend,' he said. "
