"A little chap, who ran away immediately, sir."

Wallion made a sign to the man to leave the room, and proceeded to undo the parcel. It contained five wooden dolls, exact facsimiles of those with which they were already only too well acquainted. Wallion picked up a card on which was written, in a fine female hand:

"If you want to hear more about these dolls come to the West Seattle railway station one hour after midnight."

"What on earth is it?" said Tom, rather scared.

"'Welcome to Seattle,'" said Wallion, bursting into a fit of grim merriment. "A few playthings to amuse us whilst we are waiting."

He examined the figures minutely one by one. Under the foot of each he found a number; these were respectively: 1, 3, 7, 9 and 11.

"Uneven numbers only," he grunted; "with the one we took out of the girl's satchel the series from one to eleven would be complete. Yes, that is rather puzzling; an unknown giver," he said with a sardonic smile, looking at the card once more. "H—m, West Seattle station at one o'clock in the morning." He tore the card to pieces. "No," he said in a hard voice, "that trap is not good enough. Put those images into a bag, Tom ... we'll have another look at them later on."

He paced up and down the room for a time, deep in thought; then he spoke: "They want to keep us out of the way till to-morrow, that is why they want us to keep the appointment to-night; Tom, I shall require your assistance; I mean to pay a little surprise visit to the doctor and his friends to-night."
