“Why is that, Inspector?”

He leaned forward. “Drood—or the monster that calls itself Drood—appeared and began its depradations upon my watch, Mr Collins. Quite literally upon my watch. I had just become Chief of the Detective Branch of Scotland Yard, taking over from Inspector Shackell… it was 1846, sir… when Drood’s reign of terror began.”

“Reign of terror?” I repeated. “I do not remember reading in the newspapers about any such reign of terror.”

“Oh, there’s lots of horrors that happen in those dark parts of town you and Mr Dickens went voyaging into in July that don’t end up in the newspapers, Mr Collins. You can be assured of that.”

“I’m sure you’re right, Inspector,” I said softly. The cigars were close to being smoked in their entirety. When they were, I would claim the press of creative business and show the retired old policeman to the door.

He leaned forward again and this time his active finger was pointed at me. “I need to know what you and Mr Dickens discovered about Drood that night, Mr Collins. I need to know everything.”

“I do not see how that is your concern, Inspector.”

Field smiled then and it was a broad enough smile to rearrange his ageing face into an entire new complexity of wrinkles, folds, and planes. It was not a warm smile. “It is my concern, Mr Collins, in ways that you cannot and could not ever comprehend. And I will have this information in all its details.”

I sat straight in my chair, feeling the pain from my rheumatical gout fuel my displeasure and impatience. “That sounds like a threat, Inspector.”

The smile grew wider. “Inspector Charles Frederick Field, either of the police Detective Bureau or of his own Private Enquiry Bureau, does not make threats, Mr Collins. But he will have the information he requires to carry on his battle with an old and implacable foe.”

“If this… Drood… has been your foe, as you put it, for almost two decades, Inspector, you hardly need our help. You must know much more about… your foe… than Dickens or I ever will.”

“Oh, yes, sir,” agreed Field. “I do. I would blush to say that I know more about the creature you call Drood than does any man now living. But Hatchery informs me that Mr Dickens has had recent contact with the entity. And out of Undertown. At the Staplehurst accident, to be precise. I need more information about that and about what the two of you saw in Undertown in July.”

“I thought the arrangement, or at least Detective Hatchery explained it as such, was for you police and private detectives to leave the denizens of Undertown alone as long as they continue to leave us surface dwellers to our own devices,” I said drily.

Field shook his head. “Drood don’t leave us alone,” he said softly. “I know for a fact that the creature has been responsible for more than three hundred murders in London alone since I first crossed his trail twenty years ago.”

“Good God,” I said. The shock was real. I felt it coursing through me like a full glass of laudanum.

The inspector nodded. “I need to have the information from your amateur search, Mr Collins.”

“You will have to ask Mr Dickens for any information,” I said stiffly. “It was his outing. Drood was of his interest. I assumed from the beginning that our ‘outing’— as you put it—with Detective Hatchery was part of some research that Dickens is doing for a future novel or story. I still assume that to be the case. But you will have to speak to him, Inspector.”

“I went to speak to him as soon as I returned to London after my long absence and heard from Hatchery the reason for Dickens having hired him,” said Field. He rose and began pacing, walking back and forth in front of my desk. His corpulent finger was first at his mouth, then to his ear, then alongside his nose, then touching the stone egg on my desk or the ivory tusk on my bookshelf or the Persian dagger on the mantel. “Mr Dickens was in France and unavailable. He has just returned and I interviewed him yesterday. He gave me no information of any use.”

“Well, Inspector…” I said, opening my hands. I set my cigar on the edge of the brass tray on my desk and rose. “You see then that there could be nothing I could add to help you. It was Mr Dickens’s research. It is Mr Dickens’s…”

He pointed at me. “Did you see Drood? Were you in his presence?”

I blinked. I remembered being awakened from my slumber on the subterranean brick wharf—my watch showed that it was twenty minutes after the sunrise above, after the time at which Hatchery had said he must leave—when Dickens returned in the flat-bottomed boat with the two tall and silent oarsmen. He had been gone for more than three hours. Despite the real danger, despite the real risk of being attacked and eaten by the wild boys, I had dozed off while sitting cross-legged there on the damp bricks, the loaded and cocked revolver still on my lap.

“I saw no one of Mr Drood’s alleged description,” I said stiffly. “And that is all the information I intend to impart on this subject, Inspector Field. As I said and shall repeat to you for the last time, it was Mr Dickens’s outing, his research, and if he chooses not to share the details of the evening, then I am, as a gentleman, bound to a corresponding silence. I wish you good day, Inspector, and also wish you good luck on your…”

I had come around the desk and opened the door for the ageing inspector, but Field had not budged from his place standing by my desk. He smoked the cigar, looked at it, and said quietly, “Do you know why Dickens was in France?”

“What?” I was sure that I had heard wrong.

“I said, Mr Collins, do you know why Charles Dickens was in France this week past?”

“I have no idea,” I said, voice almost brittle with irritation. “Gentlemen do not pry into other gentlemen’s travel or business arrangements.”

“No, indeed, they do not,” said Inspector Field and smiled again. “Dickens was in Boulogne for a few days. More specifically, he divided his time between Boulogne and the tiny village a few miles south of Boulogne, a place called Condette, where for some years, since 1860 to be precise, Mr Dickens has leased the former modest chalet and gardens of a certain Monsieur Beaucourt-Mutuel. This chalet in Condette has been the frequent residence of a certain actress, now twenty-five years of age, named Ellen Ternan, along with her mother. Charles Dickens has enjoyed their company at Condette—some of the visits have been up to a week in length—more than fifty times since he purportedly leased, although in truth purchased, the chalet in 1860. You may want to close the door, Mr Collins.”

I did so but remained standing by the closed door, thunderstruck. Counting Ellen Ternan, her mother, Dickens, and myself, there were no more than eight people in the world who had any hint of the chalet in Condette or the reason for Dickens’s many visits there. And were it not for my brother Charles’s being married into the Dickens household, I would never have learned about it myself.

Inspector Field resumed his pacing, his finger by his ear as though he were hearing facts whispered to him from the digit. “Miss Ternan and her mother live full-time in England, now, of course, since the Staplehurst accident in June. We can assume that Mr Dickens was winding up their affairs—and his own—at the chalet in Condette during his recent four days in Boulogne. To do this, Mr Dickens had to retrace—precisely— the same route that he took when the Staplehurst accident occurred. We both know, Mr Collins, that this could not have been easy on Mr Dickens’s nerves… which have not been strong since the accident.”

“No,” I said. What in the blazes did the man want?

“After his time in Boulogne,” continued the apparently indefatigable old man, “Dickens went on to Paris for a day or two. A more suspicious mind than mine might suggest that the Paris trip was to cover his tracks, as some detectives like to say.”
