"Moxton!" said Ellis to himself, when this idea occurred to him. "So this is where he went night after night." He examined the dates of the programmes. "Yes! all within the last three months, one night after another. H'm! Mrs. Moxton said that she did not know where her husband went, yet these programmes must have informed her even if he held his tongue. Extraordinary woman! I can't understand her actions or denials."
Failing to find the will on the shelves, Ellis examined the books. One of these, a fat little brown volume, entitled, _The Universal Informer_, was inscribed on the flyleaf, "Janet Gordon, from her father, Thomas Gordon, Edinburgh," both of which names were unknown to Ellis. The book opened of itself at a turned-down page, on which was set forth a list of the towns and cities of the world. Now, what struck Ellis as strange was the fact that the turned-down page was towards the end of the list, and contained the towns beginning with "Z." This was one of the letters concealed in the blood signs, and to say the least it is not a letter generally used. Wondering if he was on the track of a discovery, Ellis glanced down the page. His eye caught the word "lizard," and he eagerly read the paragraph in which it was contained. Four lines informed him that "Zirknitz is a town in Austria, and that in its environs is found a peculiar species of lizard." Ellis reflected. "On the arm was the letter 'Z' concealed in a sign, and the representation of a lizard. This book, which opens of itself at this particular page, mentions an Austrian town called Zirknitz and a peculiar lizard. There must be some connection between the murder and this paragraph, but I can't see it myself. What can an Austrian town have to do with the crime in Jubilee Road?"
Finding no answer to this question he pursued his search. The old-fashioned books seemed to belong to Thomas Gordon, of Edinburgh, but in one or two he had inscribed their presentation to his "daughter Janet," or to his "daughter Laura."
"Laura!" murmured Ellis. "That is Mrs. Moxton's name. Perhaps she is the Laura Gordon who owns these books. In fact, she must be. If so, she has a sister Janet; it is the first I have heard of her sister. Hullo, what's this?"
