"Yes, my lord." He draped the robe over one arm and dropped the button into a pouch at his belt. "I can tell you one thing, my lord. You talk about an evil miasma, this room has got it!" He held up the object in his hand. "There's an underlying background—something that has been here for years, just seeping in. But on top of that, there's a hellish big blast of it superimposed. Fresh it is, and very strong."
"I shouldn't be surprised, considering there was murder done here last night—or very early this morning," said Lord Darcy.
"Hm-m-m, yes. Yes, my lord, the death is there—but there's something else. Something I can't place."
"You can tell that just by holding that bronze cross in your hand?" Sir Pierre asked interestedly.
Master Sean gave him a friendly scowl. "'Tisn't quite a cross, sir. This is what is known as a crux ansata. The ancient Egyptians called it an ankh. Notice the loop at the top instead of the straight piece your true cross has. Now, your true cross—if it were properly energized, blessed, d'ye see—your true cross would tend to dissipate the evil. The ankh merely vibrates to evil because of the closed loop at the top, which makes a return circuit. And it's not energized by blessing, but by another ... um ... spell."
"Master Sean, we have a murder to investigate," said Lord Darcy.
The sorcerer caught the tone of his voice and nodded quickly. "Yes, my lord." And he walked rollingly away.
"Now where's that secret stairway you mentioned, Sir Pierre?" Lord Darcy asked.
"This way, your lordship."
He led Lord Dacy to a wall at right angles to the outer wall and slid back another tapestry.
