“I mean nothing,” replied Mr. Ludgrove swiftly. “I am trying to make you both see one aspect of this matter which has caused me much anxiety for some time. The counters were marked with a pen and ink exactly similar to those you have in your office, Ted. The envelopes in which they were sent are exactly the same as the ones you possess and have used for many years. The addresses were typed with a Planet machine, which, according to Miss Tovey, are not to be found in every office. Finally, the letters were posted in this district, W.2. You cannot fail to see the inference which must infallibly be drawn.”

“But, good heavens, the idea’s absurd!” broke in Ted. “You mean that the counters were sent out from our place!” He laughed mirthlessly, while Ivy stared at the grave face of the old herbalist, only half comprehending.

“You, Ted, have seen at least one of these counters,” continued Mr. Ludgrove, in a quiet and solemn voice. “Do you remember ever seeing anything like it before?”
