He read carefully the reports of thefts from passenger boats. They seemed to vary, but in no particular pattern that he could detect. There were various other crimes, some very serious. One Durban had written on for many pages, and it had apparently disturbed him greatly. The writing was sprawling and many of the letters only half formed. There was a kind of jaggedness to it.

Monk read it because the urgency in it held him. It had nothing to do with theft or with passenger boats at all. It concerned the murder of a prosperous man in his early forties. His body had been found in the river, apparently shot to death some time the night before and dumped into the water. He was identified as Roger Thorwood, of Chelsea, a barber of considerable wealth and influence. He was mourned by his wife, Beatrice, and three surviving children.

Durban had put a great deal of time and energy into the investigation and followed every lead. His hope and frustration were clearly marked in his notes. But after nearly three months he had learned nothing of value and been obliged to abandon his concentration on it and turn his entire attention to other duties. The death of Roger Thorwood remained a mystery. Durban's last entry on the subject was scribbled and in places almost illegible.

I have spoken to Mrs. Thorwood for the last time. There is nothing more I can do. All trails are closed. They had either nowhere or into a hopeless morass. I never thought I would say of any murder that it is better left, but I do of this. And it is wrong to expect Orme to carry the responsibility here any longer. It is not even as if one day he might be justly rewarded for his work or his loyalty. He owes it not to me, but because that is his nature, nonetheless I am profoundly grateful to him. There is no more to say.

Monk stared at the page. It was oddly difficult to turn over and continue with the murders, robberies, fights, and accidents that occurred later. There was something painfully unfinished about it, not only the mystery of Roger Thorwood s death but Durban's obvious involvement. His anger and disappointment were there, and something else less obvious, which he was too guarded to name. Guarding someone else, or himself?

There was also his oblique reference to Orme never receiving appropriate recompense for his work. It seemed he had covered for Durban as well as for Monk. It raised the question again as to why he had not received the promotion his skill had earned him. It seemed that Durban knew the reason. Monk realized that perhaps he ought to, in order to make a better judgment of Orme. But he was glad there was no time to search now.
