Not his sort

 Now that the girl had come closer, Mr. Gedge was able to see that, though beautiful, she was not altogether the sort of girl he would have cared to be left alone with for long. There was that about her which would have rendered any male uneasy. In her lustrous eyes he observed a look which he had sometimes detected in those of his wife - the look that spells trouble. If she had come to St. Rocque to meet some member of his own sex, he did not envy that member.
