her to slip through his fingers and tried to arrest Brinn!"
"What? Arrest him!" cried Innes.
"Precisely. But I rather fancy," added the inspector, grimly, "that Mr. Stokes will think twice before taking leaps like that in the dark again."
"You say he tried to arrest him. What do you mean by that?"
"I mean that Nicol Brinn, leaving Stokes locked in his chambers, went out and has completely disappeared!"
"But the woman?"
"Ah, the woman! There's the rub. If he had lain low and followed the woman, all might have been well. But who she was, where she came from, and where she has gone, we have no idea."
"Nicol Brinn must have been desperate to adopt such measures?"
Detective Inspector Wessex nodded.
"I quite agree with you."
"He evidently had an appointment of such urgency that he could permit nothing to stand in his way."
"He is a very clever man, Mr. Innes. He removed the telephone from the room in which he had locked Stokes, so that my blundering assistant was detained for nearly fifteen minutes—detained, in fact, until his cries from the window attracted the attention of a passing constable!"
