Murder In Black Letter, Chapter 18

Murder In Black Letter, 18.

you can try that on the switchboard girl for recognitionor. Does the phone office keep records of such things?

Should this passage read:

"'...you can try that on the switchboard girl for recognition or does the phone office keep records of such things?'"?

"This time he had two metal legs and he paid.

Metal legs?

This is that chapter in a detective novel where past events are summarized and explained and it is recognized that incidental incidents were in fact clues, e.g.:

when I told him Margery's place had already been raided, it was a shock

Yes, that character did respond with surprise or shock at that point in the conversation in a previous chapter. That obviously meant something although I had no idea what.

This chapter ends as follows, with Yamamura's pov:

Kintyre and Yamamura speak by phone;
Kintyre breaks off in mid-sentence;
his voice trails off;
his receiver crashes down;
he rings back to say that he has just rung someone who should have been home but there was no answer....

Another moment of realization and another possible murder...

I am summarizing the structure rather than the content of a detective novel.
