"I thought it my duty to see you, Mr. Johnson, and to tell you that it is a very nasty case. Your wife's heart is not strong, and she has some symptoms which I do not like. What I wanted to say is that if you would like to have a second opinion I shall be very glad to meet any one whom you might suggest." Johnson was so dazed by his want of sleep and the evil news that he could hardly grasp the doctor's meaning. The other, seeing him hesitate, thought that he was considering the expense. "Smith or Hawley would come for two guineas," said he. "But I think Pritchard of the City Road is the best man." "Oh yes, bring the best man," cried Johnson. "Pritchard would want three guineas. He is a senior man, you see." "I'd give him all I have if he would pull her through. Shall I run for him?" "Yes. Go to my house first and ask for the green baize bag. The assistant will give it to you. Tell him I want the A.C.E. mixture. Her heart is too weak for chloroform. Then go for Pritchard and bring him back with you." It was heavenly for Johnson to have something to do and to feel that he was of some use to his wife. He ran swiftly to Bridport Place, his footfalls clattering through the silent streets, and the big dark policemen turning their yellow funnels of light on him as he passed. Two tugs at the night-bell brought down a sleepy, half-clad assistant, who handed him a stoppered glass bottle and a cloth bag which contained something which clinked when you moved it. Johnson thrust the bottle into his pocket, seized the green bag, and pressing his hat firmly down ran as hard as he could set foot to ground until he was in the City Road and saw the name of Pritchard engraved in white upon a red ground. He bounded in triumph up the three steps which led to the door, and as he did so there was a crash behind him. His precious bottle was in fragments upon the pavement. For a moment he felt as if it were his wife's body that was lying there. But the run had freshened his wits and he saw that the mischief might be repaired. He pulled vigorously at the night-bell. "Well, what's the matter?" asked a gruff voice at his elbow. He started back and looked up at the windows, but there was no sign of life. He was approaching the bell again with the intention of pulling it, when a perfect roar burst from the wall. "I can't stand shivering here all night," cried the voice. "Say who you are and what you want or I shut the tube." Then for the first time Johnson saw that the end of a speaking tube hung out of the wall just above the bell. He shouted up it-- "I want you to come with me to meet Doctor Miles at a confinement at once." "How far?" shrieked the irascible voice. "The New North Road, Hoxton." "My consultation fee is three guineas, payable at the time." "All right," shouted Johnson. "You are to bring a bottle of A.C.E. mixture with you." "All right! Wait a bit!"
