Explore "The Sign of the Stranger" by William le Queux on Textopian. Read with annotations and highlights.
On reference to the checker-board which my friend had sent me, I found that the word "Lolita" read 31. 34. 31. 24. 44. 11.
These numbers I began to subtract from the first six numbers of the secret message, but the letters represented by the remaining numbers were a mere unintelligible jumble. At last, however, after considerable thought, I tried taking the numbers down the columns: -- namely 63. 49. 46. 68. Subtracted by the keyword there remained 32. 15. 15. 44., which I found on reference to my checker-board was the word "meet."
