"Another point was that young Glanedale happened to remark that his step-mother was much addicted to bridge, and that the stakes were too high to admit of his joining in. Also that men who have themselves accumulated their wealth know the value of money. Sir Roger disliked bridge and probably kept his lady short." "Most likely," agreed Mr. Goodge. "He has the reputation of being a bit shrewd in money matters. When did you begin to suspect Lady Glanedale?" "From the first," was the reply. "Everything rang false. Lady Glanedale's story suggested that it had been rehearsed until she had it by heart," continued Malcolm Sage. "It was too straightforward, too clearly expressed for the story of a woman who had just lost eight thousand pounds' worth of jewels. When I put questions to her she hesitated before replying, as if mentally comparing her intended answer with what she had already told. "Then she was so practical in preparing a list of the lost jewels at once, and in warning her stepson not to go near the spot beneath her window, as there might be footprints; this at a time when she was supposed to be in a state of great excitement." "Did you suspect young Glanedale at all?" queried Mr. Grimwood. "No," said Malcolm Sage, "but to make quite sure I cast doubt upon the possibility of anyone climbing the pipe. If he had been concerned he would not have volunteered to prove I was wrong." "True," said Mr. Goodge as he examined critically the glowing end of his cigar. "Lady Glanedale seems to have done the job very clumsily, now that you have explained everything." "Even the professional criminal frequently underrates the intelligence of those whose business it is to frustrate him; but Lady Glanedale's efforts in marking the water-pipe would not have deceived a child. A powerful magnifying-glass will show that on all such exterior pipes there is an accumulation of dust, which would be removed from a large portion of the surface by anyone climbing either up or down. Lady Glanedale had thought marks made by a boot or a shoe would be sufficient confirmation of her story. She is rather a stupid woman," he added, as he rose to go. "I suppose she got the idea from the Comminge affair?" "Undoubtedly," was the response; "but as I say, she is a stupid woman. Vanity in crime is fatal; it leads the criminal to underrate the intelligence of others. Lady Glanedale is intensely vain." "The Board will probably want to thank you personally," said Mr. Goodge as he shook hands; "but I'll try and prevent them from giving you another walking-stick," he laughed as he opened the door.
