"No, I say it. Redway's a fool, you know. Look how he blundered in that robbery in Northampton a year ago. I only wish we could get a man from Scotland Yard. He'd nab the murderer before the day is out." At heart I did not endorse this wish. On the contrary the discovery of this footmark that had escaped me was certainly a very serious _contretemps_. My endeavours must, I saw, now all be directed towards arranging matters so that, if necessary, Lolita could prove a complete _alibi_. "Do you know," went on the doctor, "there's one feature in the affair that's strangest of all, and that is that there seems to have been an attempt to efface certain marks, as though the assassin boldly returned to the spot after the removal of the body and scraped the ground in order to wipe out his footprints. Redway won't admit that, but I'm certain of it--absolutely certain. I suppose the ass won't accept the theory because it isn't his own." I tried to speak, but what could I say? The words I uttered resolved themselves into a mere expression of blank surprise, and perhaps it was as well, for the man before me was as keen and shrewd as any member of the Criminal Investigation Department. He was essentially a man of action, who whether busy or idle could not remain in one place five minutes together. He rushed all over the country-side from early morning, or dashed up to London by the express, spent the afternoon in Bond Street or the Burlington, and was back at home, a hundred miles distant, in time for dinner. He was perfectly tireless, possessing a demeanour which no amount of offence could ruffle, and an even temper and chaffing good-humour that was a most remarkable characteristic. The very name of Pink in Northamptonshire was synonymous of patient surgical skill combined with a spontaneous gaiety and bluff good-humour. "I've given over that bit of white fur to Red way," he went on. "And I expect we shall find that the owner of it is also owner of the small shoes. I know most of the girls of Sibberton--in fact, I've attended all of them, I expect--but I can't suggest one who would, or even could, wear such a shoe as that upon the woman who was present at the tragedy, if not the actual assassin." "Redway will make inquiries, I suppose?" I remarked in a faint hollow voice. "At my suggestion he has wired for assistance, and I only hope they'll get a man down from London. If they don't--by Gad! I'll pay for one myself. We must find this woman, Woodhouse," he added, rising and tossing his cigarette-end into the grate. "We'll find her--at all costs!" CHAPTER SEVEN. IS FULL OF MYSTERY. The doctor's keen desire to solve the mystery caused me most serious apprehension. His bluff good-humour, at other times amusing, now irritated me, and I was glad when he rose restlessly and went out, saying that he had wired to Doctor Newman at Northampton, and that they intended to make the post-mortem at two o'clock.
