Once again his face took on a look of pained amusement. “No, you don’t. But I think you’re about to appreciate it.”

He opened his desk drawer and took out an oversized beige file. Pasted on the top left corner of the cover was a white label containing the name of the subject of the file and the name of the agency and department responsible for maintaining the file. The name on the file was mine.

“This is your police personnel file. All police have one. And all ex-policemen, such as yourself.” Schuchardt opened the file and removed the first page. “The index sheet. Every item added to the file is given a number on this sheet of paper. Let’s see. Yes. Item twenty-three.” He turned the pages of the file until he found another sheet of paper, and then handed it to me.

It was an anonymous letter denouncing me as someone with a Jewish grandparent. The handwriting seemed vaguely familiar, but I hardly felt up to the task of trying to guess the author’s identity in front of Otto Schuchardt. “There seems to be little point in me denying this,” I said, handing it back.

“On the contrary,” he said, “there’s every point in the world.” He struck a match, put the flame to the letter, and let it drop into the wastepaper bin. “Like I said before, I don’t forget my friends.” Then he took out his fountain pen, unscrewed the top, and wrote in the “Remarks” section of the index sheet. “No further action possible,” he said as he wrote. “All the same, it might be best if you were to try and fix this.”

“It seems a bit late now,” I said. “My grandmother has been dead for twenty years.”

“As someone of second-grade mixed race,” he said, ignoring my facetiousness, “you may well find, in the future, that certain restrictions are imposed on you. For example, if you were to try and start up a business, you could be required, under the new laws, to make a racial declaration.”

“Matter of fact, I’d been thinking of starting up as a private investigator. Assuming I can raise the money. Being the house detective at the Adlon is kind of slow after working Homicide at the Alex.”
