“I’d like to make an appointment to see you, sir.”
“Why?”
“I can’t discuss the matter over the phone, sir. Either I could come to you, or you could visit me at Scotland Yard, whichever is more convenient.”
“I’ll come to you.”
Sloane shrugged his shoulders.
“I’ve had both those tapes analyzed by an American voice specialist,” said Stokes, “and he’s confirmed that not only were they made by the same person, but from the same telephone.”
“That’s ridiculous.”
“Are you sure?” asked the interrogator, his eyes never leaving Sloane.
“Yes, I am, because the telephone call to the customs officer lasted less than three minutes, and is therefore untraceable.”
“How could you possibly know that, Mr. Sloane, if it wasn’t you who made the call?”
“Because I attended every day of Hakim Bishara’s trial and heard all the evidence firsthand.”
“You did indeed, sir. And I confess I’m still puzzled about why you did.”
“Because, Mr. Stokes, as I’m sure you know, I was the previous chairman of Farthings Bank, and one of my clients at the time was a substantial shareholder, so I was doing no more than my fiduciary duty. You’ll need something a little more convincing than that to prove I was involved.”
“Before we go on to discuss the role you played on behalf of your substantial shareholder, and how you were both involved, perhaps I could play the first tape again. I’m going to ask you to listen more carefully this time.”
Sloane could feel the palms of his hands sweating. He wiped them on his trousers as the tape recorder whirred back into action.
“Customs office, Heathrow.”
“Put me through to the senior customs officer.”
“May I ask who’s calling?”
“No, you may not.”
“I’ll see if he’s available.”
Stokes pressed the Stop button. “Listen carefully, Mr. Sloane.” The chief inspector pressed the Play button once again, and this time Sloane could hear the faint sound of chimes in the background. Stokes pressed Stop.
“Ten o’clock,” he said, his eyes still fixed on Sloane.
“So what?”
“Now I’d like you to listen to the second tape again,” said Stokes as he swapped the cassettes. “Because I called you in your office at one minute to ten.”
“Is this Adrian Sloane?”
“Depends who’s asking.”
A long pause, and this time Sloane couldn’t miss the ten chimes. He felt beads of sweat on his forehead and, despite having a handkerchief in his top pocket, made no attempt to wipe them away.
The detective pressed Stop. “And I can assure you, Mr. Sloane, those chimes came from the same clock, which our American expert has confirmed is St. Mary-le-Bow, Cheapside, less than a hundred yards from your office.”
“That proves nothing. There must be thousands of offices in the vicinity, and you know it.”
“You’re quite right, which is why I requested a court order to allow me to check your phone records for that particular day.”
