“Of course, Admiral.”

Mrs. Mishra ushered Jenny out and Travers said to the policewoman, “There’s a chance there could be more to this than meets the eye, officer. I’ll just make a phone call and I’ll be with you directly.”

“Smith and Johnson,” Ferguson said. “That’s a good one.”

“Seems like a run-of-the-mill daytime robbery, sir,” Lane said. “All the usual hallmarks. They only took the kind of portable items that convert to quick cash. The television, video and the rest.”

“Rather sophisticated, I would have thought, having their very own Telecom van.”

“Probably stolen, sir. We’ll run a check.”

“Rather fortunate I relieved Travers of the diary and the translation software he’d made from it if they were looking for something more important than television sets.”

“You really think it could have been that, sir?”

“All I know is that I learned a long time ago to suspect coincidence, Jack. I mean, how often does Garth Travers leave the house at seven-thirty in the morning? They must have seen him go.”

“And you think taking the run-of-the-mill kind of stuff was just a blind?”

“Perhaps.”

“But how would they know about the existence of the diary, sir?”

“Yes, well that is the interesting point.” Ferguson frowned. “I’ve had a thought, Jack. Go to Lord North Street. Get one of your old friends from Special Branch, someone who specializes in bugging devices, to do a sweep.”

“You really think…?”

“I don’t think anything, Jack, I’m merely considering all the options. Now on your way.”

Lane went out and Ferguson picked up the phone and rang Lord North Street and spoke to Travers. “How’s your guest?”

“Fine. Bearing up remarkably well.”

Ferguson looked at his watch. “Bring her to my place in Cavendish Square at about twelve-thirty. We might as well get on with it, but don’t say a word. Leave it all to me.”

“You can rely on me.”

Travers put the phone down and went into the living room, where Jenny sat by the fire drinking coffee. “Sorry about all this,” he said, “a hell of an introduction.”

“Not your fault.”

He sat down. “We’ll go out soon for a spot of lunch, but I’d like to introduce you to an old friend of mine, Brigadier Charles Ferguson.”

She was an astute young woman and sensed something at once. “Did he know Henry?”

“Not directly.”

“But this is something to do with Henry?”

He reached across and patted her hand. “All in good time, my dear, just trust me.”

Santiago was still at his suite at the Ritz when the man who called himself Smith phoned through from London. “Not a thing, guv, certainly nothing like you described.”

“Hardly surprising, but it was worth checking,” Santiago said. “A nice clean job, I trust.”

“Sure, guv, just made it look run-of-the-mill. I tapped the phone, just in case you wanted to listen in.”

“You did what?” Santiago was coldly angry. “I told you, these are Intelligence people involved in this one, the kind of people who check everything.”

“Sorry, guv, I thought I was doing the right thing.”

“Never mind, it’s too late now. Just drop any other commissions you have at the moment and wait to hear from me,” and Santiago put the phone down.

In the living room at Cavendish Square Jenny sat beside the fire opposite Ferguson and Travers stood by the window.

“So you see, Miss Grant,” Ferguson said, “there will have to be a coroner’s inquest, which is set for the day after tomorrow.”

“And I can have the body then?”

“Well that is really a matter for the next of kin.”

She opened her handbag and took out a paper, which she unfolded and passed to him. “Henry took up serious diving a year or so ago.”

“Rather old for that, I should have thought,” Ferguson said.

“Yes, well he had a near-miss one day. Ran out of air at fifty feet. Oh, he made it to the surface okay, but he immediately went to his lawyer and had him draw up a power of attorney in my name.”

Ferguson looked it over. “That seems straightforward enough. I’ll see that it’s passed to the coroner.” He reached down at the side of the sofa and produced Friemel’s aluminium briefcase. “Have you seen this before?”

She looked puzzled. “No.”

“Or this?” He opened it and took out the diary.

“No, never.” She frowned. “What is this?”

Ferguson said, “Did Mr. Baker tell you why he was coming to London?”

She looked at him, then turned to glance at Travers, then she turned back. “Why do you think he came here, Brigadier?”

“Because he discovered the wreck of a German submarine somewhere off St. John, Miss Grant. Did he tell you about that?”

Jenny Grant took a deep breath. “Yes, Brigadier, he did tell me. He said he’d been diving and that he’d discovered a submarine and a briefcase.”

“This case,” he said, “with this diary inside. What else did he tell you?”

“Well, it was in German, which he didn’t understand, but he did recognize the name Martin Bormann and…” Here she paused.

Ferguson said gently, “And…?”

“The Duke of Windsor,” she said lamely. “Look, I know it sounds crazy but…”

“Not crazy at all, my dear. And where did Mr. Baker find this U-boat?”

“I’ve no idea. He wouldn’t tell me.”

There was a pause while Ferguson glanced at Travers. He sighed. “You are absolutely certain of that, Miss Grant?”

“Of course I am. He said he didn’t want to tell me for the time being. He was very excited about his find.” She paused, frowning. “Look, what are you trying to tell me, Brigadier? What’s going on here? Does this have something to do with Henry’s death?”

“No, not at all,” he said soothingly and nodded to Travers.

The Admiral said, “Jenny, poor old Henry’s death was a complete accident. We have plenty of witnesses. He stepped into the path of a London Transport bus. The driver was a sixty-year-old Cockney who won the Military Medal for Gallantry in the Korean War in nineteen fifty-two as an infantry private. Just an accident, Jenny.”

“So, you’ve no idea where the U-boat lies?” Ferguson asked again.

“Is it important?”

“Yes, it could be.”

She shrugged. “I honestly don’t know. If you want my opinion, it would have to be somewhere far out.”

“Far out? What do you mean?”

“Most of the dive sites that tourists use from St. Thomas and St. John are within reasonable distance. There are plenty of wrecks around, but the idea that a German U-boat had remained undiscovered since the end of the war,” she shook her head, “that’s nonsense. It could only happen if it was somewhere remote and far out.”

“Further out to sea.”

“That’s right.”

“And you’ve no idea where?”

“No, I’m not much of a diver, I’m afraid. You’d need to go to an expert.”

“And is there such a person?”

“Oh, sure, Bob Carney.”

Ferguson picked up his pen and made a note. “Bob Carney? And who might he be?”

“He has the watersports concession at Caneel Bay Resort. I mean, he spends most of his time teaching tourists to dive, but he’s a real diver and quite famous. He was in the oil fields in the Gulf of Mexico, salvage work, all that stuff. They’ve done magazine articles about him.”

“Really?” Ferguson said. “He’s the best diver in the Virgin Islands then?”

“In the whole Caribbean, Brigadier,” she said.

“Really.” Ferguson glanced at Travers and stood up. “Good. Many thanks for your cooperation, Miss Grant. I appreciate this is not a good time, but you must eat. Perhaps you’ll allow me to take you and Admiral Travers out for a meal tonight.”

She hesitated and then said, “That’s kind of you.”

“Not at all. I’ll send my car to pick you up at seven-thirty.” He ushered them to the outside door. “Take care.” He nodded to the Admiral. “I’ll be in touch, Garth.”
