Context

“said the older man, speaking with a hesitation which showed that he was on delicate ground. “It was kind of you to come.” “Why did you not put your name to the note?” “One has to be cautious, mister. One never knows in times like these how a thing may come back to one. One never knows either who to trust or who not to trust.” “Surely one may trust brothers of the lodge.” “No, no, not always,” cried Morris with vehemence. “Whatever we say, even what we think, seems to go back to that man McGinty.” “Look here!” said McMurdo sternly.” source
