much chance of getting away from the police while carrying an infant of that age, soââ
What of the womanâs fear?
If this had been planned cold-bloodedly, if parents simply wanted to be free from the child, would the woman have sounded so frightened? And remember the talk of the Doc.
Rollison reached a decision.
He lifted the receiver again, and dialled Whitehall 1212. When a brisk-voiced operator said: âScotland Yard,â he asked at once:
âSuperintendent Grice isnât there by any chance, is he?â
âNo, sir, Iâm afraid not.â
âChief Inspector Worley?â
âNo, sir.â
âChief Inspector Knott?â
âYes, sir, heâs in his office. Who shall I tell him is calling?â
âRichard Rollison.â
âRichard Rolââ echoed the operator, and then stopped abruptly, only to go on in a different tone: âMr. Rollison, yes sir. Iâll put you through at once.â
âThanks very much,â said Rollison warmly.
Knott was a youngish man, only recently promoted, and was particularly well-disposed, because a few months earlier he had arrested a murderer in what was generally accepted as a very smart piece of work; hence his promotion. He was well aware that he would not have made the arrest but for the Toff, and was not likely to stand on ceremony.
âHallo, Rollison, canât you sleep?â Knott had a lively voice. âWhatâs the trouble?â
âItâs my guilty conscience and a curious telephone call,â said Rollison mildly.
âCanât do anything about your conscience,â said Knott; it was easy to imagine his grin. âWhat information do you want about the telephone call?â
âThe number in Guildford, hence the address,â Rollison told him. âThe Supervisor is getting both, but wonât confide in an ordinary humble citizen. If I tell her to refer to the Yard, she might decide to trust me.â
âAnd she might also check with us,â said Knott dryly. âAll right, you can give us as a reference. Whatâs it all about?â
âWhen Iâve found out, Iâll tell you.â
âI hope you mean that! How did the American trip go, by the way? I read bits and pieces about you; you seem to have taken New York by storm.â
âIn fact they took me by the seat of my pants, but I survived,â said Rollison, and took advantage of Knottâs expansive mood. âThe trouble is that Iâm out of touch over here, just now.â
âExactly what else do you want to know?â
Rollison chuckled.
âGo on like this, and Iâll begin to think you earned your promotion after all! What kind of a reputation has the Doc won for himself lately?â
There was a long pause, so long that it seemed ominous. Then at last: âNasty,â said Knott, and his voice sharpened noticeably. âThere was another ugly killing in Shadwell five weeks ago, not much doubt that the Doc did it, or else he was behind it. We didnât put an end to him when we hanged Jessie Gay. Is thisââ
âKnow who he is, yet?â
âNo.â
âWe must find out,â said Rollison, earnestly. âChief Inspector, I canât thank you enough, and if anything happens that is likely to interest you, Iâll pass it on.â
âMind you do,â said Knott. He did not sound quite so amiable now; mention of the Doc had obviously troubled him. âTake my advice, and make sure what youâre doing before you tackle anything that the Docâs involved in. Heâs reputed to have said heâll break you, for catching Jessie Gay.â
âOh, has he?â said Rollison heavily. That womanâs fear had been real fear, remember. âIâll be very careful indeed,â he promised. âGoodbye.â
He rang off, stubbed out the cigarette, which he had drawn at only three or four times, and called the
